Answer:

D. 32°

Step-by-step explanation:

C=A because the triangle is isosceles.

A+B+C=180- Sum of angles in a triangle

74+B+74 = 180

148+B=180

B=32°

Answer:

32°

Step-by-step explanation:

The triangle ABC is a isosceles so angle A = angle C

The sum of interior angles in a triangle is = 180°

74 + 74 + angle B = 180

B = 32°

andre [41]

Answer with Step-by-step explanation:

We are given that

LHS

$cos 2x$

To prove that

$cos 2x=cos^2x-sin^2 x$

$cos(x+x)$

We know that

$cos(x+y)=cos xcosy-sinx siny$

Using the formula

$cos(x+x)=cosx\cdot cosx-sinx\cdot sinx$

$cos2 x=cos^2 x-sin^2 x$

By using

$cosx\cdot cosx=cos^2 x$

$sinx\cdot sinx=sin^2 x$

LHS=RHS

Hence, proved.
