Sorry but i only know the answer for the 1st question.
--------------------------
If the angles are complementary they measure 90°.
1st find half of 90
which is 45.
Find 4 more than 45.
which is 49°
then subtract 90-49=41
so the measurement of the 2 angles are
49 and 41
Hope it helps!!
Answer:
Step-by-step explanation:
A=1/2b *h
base(b)= 5/3x
height(h) = h
1/2(5/3x)*x=
5/6x*x=
5/6x^2
Do you have a Ti-84 calculator you need one to solve this problem.
