Answer:
y = 14
Step-by-step explanation:
Since AC = BC then the triangle is isosceles and the base angles are congruent, that is
∠A = ∠B = 50°, thus
∠C = 180 - (50 + 50) ← sum of angles in Δ = 180°
= 180 - 100 = 80°, hence
5y + 10 = 80 ( subtract 10 from both sides )
5y = 70 ( divide both sides by 5 )
y = 14

Answer:
x=21
Step-by-step explanation:
add 5 to both sides. it gives u 21
Let's assume that number as x
The product of 7 and a number =7x
and then increased by 1
so, it will become
=7x+1
now, it is between 15 and 43
so, we can write as

now, we can solve for x
Since, we have to isolate x
step-1:
Subtract all the sides by 1


step-2:
Divide all the sides by 7


so, solution is
