Answer:
1. 117 sq. in.
2. 168 sq. in.
3. 99 sq. in.
Step-by-step explanation:
1. base x height = area
13 x 9 = 117 sq. in.
2. 1/2 x height x (base + base)
1/2 x 14 x (15 + 9)
1/2 x 14 x 24
Multiply 1/2 by 14 to get 7
7 x 24 = 168 sq in.
3. 1/2 d x d
1/2 x 18 x 11
Multiply 1/2 by 18 to get 9
9 x 11
Multiply 9 x 11 to get 99
9 x 11 = 99 sq. in.
Answer:
25 degrees.
Step-by-step explanation:
Reading from the diagram m < EOD = 140 - 115
= 25 degrees.
Answer:
1 1/3 I think
Step-by-step explanation:
Hope I helped :D
-28 = 3 + 8(h-9)
-28 = 3 + 8h - 72 (distributive property a(b-c) = ab - ac)
-28 = -69 + 8h (combining like terms ( 3 - 72))
41 = 8h (adding 69 on both sides to isolate 8h)
/8 /8 (dividing coefficient (8) on both sides to isolate h)
5.125 = h
Therefore h = 5.125
