Answer:
7 1/15
Step-by-step explanation:
3 2/5 + 3 4/6 = 7 1/15
The pair of angles are adjacent angles and supplementary and their measure =180
5(x + 27) >= 6(x + 26)
5x + 135 >= 6x + 156
-x >= 21
x <= -21
Answer: Choice B.
Easy you just divide it like a regular then put move the decimal to the left the number of times letters are behind it.
2 angles are complementary if the sum of their measures is 90°.
For example if m(P) = 41° and m(Q)=49°, then P and Q are complementary.
Thus A and B are complementary means that m(A)=m(B)=90°:
(3x+5°) + (2x-15°) =90°
5x-10°=90°
5x=100°
x=20°
Thus
m(A)=3x+5°=3* 20°+5°=60°+5°=65°
m(B)=2x-15°=2*20°-15°=40°-15°=25°
