Astronomers sometimes use angle measures divided into degrees, minutes, and seconds. One degree is equal to 60 minutes, and one minute is equal to 60 seconds. Suppose that ∠J and ∠K are complementary and that the measure of ∠J is 45 degrees, 30 minutes, 14 seconds. What is the measure of ∠K?
The measure of ∠K is ______ degrees, ______minutes, and _____ seconds.
Answer:
Here's what you need to know to answer this question:
If two angles are "complementary"
then they add up to 90 degrees.
So now you know that
(Angle-J) + (Angle-K) = 90 degrees .
Subtract (Angle-J)
from each side: Angle-K = (90 degrees) - (Angle-J)
Angle-K = (90 degrees) minus (48 degrees 26 minutes 8 seconds)
As soon as you do that subtraction, you have the answer.
The thing that makes it tough is subtracting some minutes
and some seconds from 90 degrees.
How you do that is: An unusual kind of regrouping ('borrowing').
Usually, when you regroup, you take '1' from a place and use it
to make '10' in the smaller place.
This time, when you take '1' from a place, it gives you '60'
in the smaller place.
-- Take 1 degree away from the 90 degrees.
Use it to make minutes.
Then you have 89 degrees 60 minutes .
-- Take 1 minute away from the 60 minutes.
Use it to make seconds.
then you have 89 degrees 59 minutes 60 seconds .
Now the subtraction is a lot easier.
89 degrees 59 minutes 60 seconds
minus 48 degrees 26 minutes 8 seconds .
That's easy to do, and the difference is the measure of Angle-K.

Answer:
60 degree
Step-by-step explanation:
They are complementary angles which means they must add up to 90.
As WOX is 30 degree then
90-30=60.
yoz would also be 60 degrees because wov and yoz are equal

Jaxon is creating a mosaic design on a rectangular
table. He has added two pieces to one of the corners.
The first piece has an angle measuring 38° and is
placed in the corner. A second piece has an angle
measuring 27° and is also placed in the corner. Draw a
diagram to model the situation. Then, write an
equation, and use it to determine the measure of the
unknown angle in a third piece that could be added to
the corner of the table.

Answer:
A. 525 in squared
Step-by-step explanation:
Fundamentally, the area of a parellelogram such as this can be calculated the same way the area of a normal rectangle is calculated: Length x Width.
Thus,
(27 + 8) x 15 = Area
35 x 15 = Area
525 = Area
Don't forget your units! (Inches squared)
2x−1/4y=1 solve for y please
Answer:
EASY DUBS:
Step-by-step explanation:
2*x-((1/4)*y) = 1 // - 1
2*x-((1/4)*y)-1 = 0
2*x+(-1/4)*y-1 = 0
2*x-1/4*y-1 = 0 // + -1/4*y-1
2*x = -(-1/4*y-1) // : 2
x = (-(-1/4*y-1))/2
x = (1-(-1/4*y))/2
x = (1-(-1/4*y))/2
What is the approximate area of this figure?
A. 25 cm
B. 31 cm
C. 38 cm
D. 42 cm
Step-by-step explanation:
4*4=16 (area of the square)
4/4 *suare root of 4* 8²-4²=
=15.492 approximately
So the whole area will be approximately
31 cm²
So the anwer is B.31 .
Kyle went to the store to purchase a hat. The hat’s normal price is $50, but he used a coupon which allowed him to save $20. What percent of the normal price does Kyle save?
