Answer:
A
Step-by-step explanation:
A]
7*5 = 35+15 = 50
10*70 = 70 +14 = 85
15*7 = 105 +15 = 120
20*7 = 140+15 = 155
B]8.50*5 = 42.5
C]10*5 = 50
10*10 = 100
D] = 8*5 = 40 +10 = 50
10*8 = 80+10 = 90
It is the third option 16x+9=4x
Answer:
Step-by-step explanation:
Putting value of z = 3
6(3)2+ 2(3) + 10
6(9) + 6 + 10
54 + 16
70
Answer:
16.64645cm²
Step-by-step explanation:
All of the angles are equal: A = B = C = 180/3 = 60°.
All of the sides are equal: a = b = c.
h = 5 cm, sin60 = h/a = 5/a, a = 5/sin60 = 5.77 cm.
Area = 1/2bh = 1/2 x 5.77 x 5.77 = 33.2929/2 = 16.64645cm²
They are adjacent angles, they don't overlap and share a common vertex.
