Answer:
see explanation
Step-by-step explanation:
Given that Bilal is age y and his mother is 25 years older, then
a. Bilal's mothers age is y + 25
b. the sum of their ages = y + y + 25 = 2y + 25
c. Mother is y + 25 = 12 + 25 = 37 years
The answer to <span>H+12.5=-12.5</span> is H=-25
The length of the side = <span>The length of the arc intercepted by the central
<span>angle
</span></span>∴ length = Θ r
where Θ = <span>central<span> angle in radians
and r = radius
∴ </span></span><span>Θ = 70° = 70 * π /180
</span><span>r = 13 in.
∴ </span>length = <span>(70 * π /180) * 13 ≈ 15.88 in.
</span>
Answer:
You add 12.5+12.5+3.02+3.02 which equals 31.04

Answer:
21°, 84°, 75° are the angles
Step-by-step explanation:
Total angle in a triangle is 180.
x + 4x + (5x - 30) = 180
10x - 30 = 180
10x = 210
x = 21°
Angles are:
A: 21°
B: 4(21) = 84°
C: 5(21) - 30 = 75°
