Question

answer needed for both qoustions please urgent with steps I will mark as brain list

Answer 1

Step-by-step explanation:

1. in triangle ABC,

AB=AC

Angle B=Angle C

we know that,

angle A+ angle B+ angle C=180

let B=C=x

60+x+x=180.

2x=180-60

2x=120

x=60.

angle B=60

angle C=60

as we know ABC is equilateral triangle

so AB=BC=CA

therefore,

BC=7.2 CM

2) let the number be x.

a/q

5x+7=37

5x=30

x=30/5=6.

number is 6.
