Question

please help with the steps

Answer 1

Answer:

45⁰

Step-by-step explanation:

two sides ab and BC are equal that is two angle angle A and angle C are equal and it is given that angle b is equal to 90 degree.

so from this we can see that angle A + angle C is equal to 90 degree and both are equal so 90 will be divided into two parts

Answer 2

Answer:

Let the base angles be x

90+x+x=180(Angle s opposite to equal sides are equal, ASP)

2x=180-90

2x=90

x=90/2

x=45

So measure of angle A is 45
