The ans is C
you have perpendicular angles so 60 is equal to the total of the equation... doing the whole math X= 20
Answer:
18.46
Step-by-step explanation:
find the area using SSS, then solve for height
Answer:
9 fewer ounces
Step-by-step explanation:
first divide 12 by 100 to get .12
then multiply that by 75 and get 9
12-9=3
Answer:
9-x
Step-by-step explanation:
To answer this item, we let x be the measure of angle Y. If we say supplement, it is understood that when we sum up the measures of the two angles (angle Y and its supplement) the answer should be 180. Therefore the other angle is 180-x. Going back to the condition given in this item, we will be able to generate an equation,
x = 3(180 - x)
The value of x from the equation is 135. Thus, m∠Y is 135°.
