Question

The bases of an isosceles triangle are represented by (5x+10) and 50° ,find x

Answer 1

x=8

Step-by-step explanation

An isosceles triangle therefore has both two equal sides and two equal angles

so, angle a= angle b

then, Let

a=5x+10

b=50

replace and solve

`\begin{gathered} 5x+10=50 \\ \text{subtract 10 in both sides} \\ 5x+10-10=50-10 \\ 5x=40 \\ \text{divide both sides by 5} \\ (5x)/(5)=(40)/(5) \\ x=8 \end{gathered}`

so,the answer is

x=8
