147º
Step-by-step explanation:
180-33=147
base = 3*3 = 9 sq. in.
side = 1/2 *3*6 = 9 sq. in.
4 sides x 9 = 36 + 9 (base) = 45 in^2
Answer is A
Y=4x-21 I’m pretty sure is the answrr.
D-7<span>≤ 3
add 7 to both sides
d</span><span>≤10</span>
Let's first turn 1 9/10 into an improper fraction, which is 19/10
so if R/12 equa;s 19/10, cross multiply
10r equals 228
divide both sides by 10, you get r= 22.8
