Answer:
x = 9
Step-by-step explanation:
110 + 3x + 11 = 16x + 4
121 + 3x = 16x + 4
<u> -3x -3x</u>
121 = 13x + 4
<u>-4 - 4</u>
117 = 13x
117 ÷ 13 = x
9 = x
Check:
110 + 3(9) + 11 = 16(9) + 4
121 + 27 = 144 + 4
148 = 148
Answer:
m<B = 115°
Step-by-step explanation:
add <A and <C, then subtract that from 180° to get <B
Answer: ASA: If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent. SAS: If any two angles and the included side are the same in both triangles, then the triangles are congruent.
Answer:
t = 2.61
Step-by-step explanation:
h (t) = (1/2) x (- 9.8) x t ^ 2 + 12 x t + 2
h (t) = -4.9 x t ^ 2 + 12 x t + 2 (rewritten)
When the ball hits the ground:
-4.9 x t ^ 2 + 12 x t + 2 = 0
Solved:
t1 = -0.16
t2 = 2.61
The negative is irrelevant here. Hence: 2.61.
