[tex]x + 105 + 113 + 75 = 360[/tex]
[tex]x + 293 = 360[/tex]
[tex]x = 360 - 293[/tex]
[tex]x = 67[/tex]
As we know that, for any shape with sides n, the sum of all it's interior angles is (n - 2) × 180°, so as the Shape ABCD is a quadrilateral with 4 sides, so sum of it's all interior angles is just going to be (4 - 2) × 180° = 2 × 180° = 360°, so if we assume the missing angle be [tex]\bf \angle A[/tex], by using the sum property we will be having ;
[tex]{:\implies \quad \sf \angle A+105{\degree}+113{\degree}+75{\degree}=360{\degree}}[/tex]
[tex]{:\implies \quad \sf \angle A+293{\degree}=360{\degree}}[/tex]

2. Since there are no parentheses or exponents, multiply first:
4*5=20

What is the area of this triangle?
Enter your
answer as a decimal in the box. Round only your final
answer to the nearest tenth. 8, 28, 7
Answers
Answer:
13.1 cm² (nearest tenth)
Step-by-step explanation:
Use the sine rule for area of a triangle with 2 sides and an included angle (SAS).
Sine rule for area
[tex]\textsf{Area ABC}=\dfrac12ab \sin C[/tex]
(where [tex]a[/tex] and [tex]b[/tex] are the side lengths and [tex]C[/tex] is the included angle)
Given:
[tex]a[/tex] = 8 cm[tex]b[/tex] = 7 cm[tex]C[/tex] = 28°[tex]\implies \textsf{Area}=\dfrac12\cdot 8 \cdot 7 \cdot\sin (28\textdegree)[/tex]
[tex]=13.14520376...[/tex]
[tex]= 13.1 \textsf{ cm}^2 \textsf{ (nearest tenth)}[/tex]
Use sine rule
Area:-
[tex]\\ \sf\longmapsto \dfrac{1}{2}Base\times Height sin\theta[/tex]
[tex]\\ \sf\longmapsto \dfrac{1}{2}(8)(7)sin28[/tex]
[tex]\\ \sf\longmapsto 28sin28[/tex]

Identify the vertex of the parabola?
Answers
Hi!
The vertex is the highest or lowest point on a graph, also known as the maximum/minimum. It is the turning point for the parabola.
In this case, it has a maximum, because the parabola points downward.
Using the graph, we can see the vertex is at point
(3, 4)
Answer:
(3,4)
Step-by-step explanation:
The vertex is a point that is the maximum or minimum of the parabola. (3,4) is the highest point on that parabola so it's a vertex

O 17 in
22 in
27 in
32 in
Answers
Answer:
22 in
Step-by-step explanation:
volume of a right prism = area of base x height
Given:
volume = 352 in³area of base = 16 in²⇒ 352 = 16 × height
⇒ height = 352 ÷ 16
⇒ height = 22 in
Height be x
Volume=Area of base×height[tex]\\ \rm\rightarrowtail 16x=352[/tex]

Which statement accurately describes the graph 2y=4x+8?
A
an increasing line that passes through (0, 4)
B
a decreasing line that passes through (0, 0)
C
an increasing line that passes through (0, 8)
D
a decreasing line that passes through (0, 2)
Answers
By rewriting the linear function we will see that the correct option is A.
"an increasing line that passes through (0, 4)"
Which statement describes the graph?
Here we have the linear function:
2y = 4x + 8
We can rewrite it to get the function in the slope-intercept form:
y = (4x + 8)/2
y = 2x + 4.
So, the slope is positive, this implies that we will have an increasing line.
We also can see that the y-intecept is 4, this means that the line passes through the point (0, 4).
From that, we can conclude that the correct option is A.

THIS IS URGENT. PLEASE HELP. given AC=30, find the value if x, and the length of BC
Answers
Answer:
The value of x is 4.8. The length of BC is 14.6.
Step-by-step explanation:
I combined the two expressions 3x+1 and 2x+5 to 5x+6=30
1. I subtracted 6 from 6 and 30 in the equations.
2. I was left with 5x=24
3. I then divide 5 from 5x and 24
4. I got x=4.8
To get the length of BC
2x+5
1. I multiplied 2×4.8
2. I got 9.6
3. I then add 5 to 9.6
4. I finally get the answer 14.6 which is the length of BC
Answer:
[tex]\overline{BC}=14.6[/tex]
Step-by-step explanation:
we know that
[tex]\overline{AC}=\overline{AB}+\overline{BC}[/tex]
so
[tex]30=3x+1+2x+5\\\\30=(3x+2x)+(1+5)\\\\30=(3+2)x+(1+5)\\\\30=5x+(1+5)\\\\30=5x+6\\\\5x+6=30\\\\5x+6-6=30-6\\\\5x+0=30-6\\\\5x=30-6\\\\5x=24\\\\\frac{1}{5}(5x)=\frac{1}{5}(24)\\\\\frac{5}{5}x=\frac{1}{5}(24)\\\\\frac{1}{1}x=\frac{1}{5}(24)\\\\x=\frac{1}{5}(24)\\\\x=\frac{24}{5}\\\\x=4.8[/tex]
and now we solve for BC
[tex]\overline{BC}=2x+5\\\\\longrightarrow x=4.8\longleftarrow \\\\\overline{BC}=2(4.8)+5\\\\\overline{BC}=9.6+5\\\\\overline{BC}=14.6[/tex]

Answers

You’re welcome good luck to whatever you’re working on. Give brainliest please for my answer.
here’s why:
in order to divide fractions, you must multiply straight across. but, only when diving, you flip the 2nd fraction. we know that 7 has an invisible 1 under it, but since we’re dividing, we must flip it to 1/7.
so, you should now hove something that looks like this;
1 1
- x -
4 7
so simply, if multiplied correctly across, you should end up with 1/28.
1 x 1 = 1
7 x 4 = 28
