Question

please answer the following question

Answer 1

Step-by-step explanation:

<Y=<Z

an angle opposite to the equal sides of a triangle are equal.

2x+7=45

2x=38

x=19 <Y=19

sum of all angles of triangle =180

angle x+y+z=180

x+19+45=180

x=180-64

<X=116

please mark answer as brainliest.

hope it would be helpful for you

Answer 2

Answer:

angle x, =x

angle y=2x+7angle z=45

x+2x+7+45=180

3x+7+45=180

3x+45.7=180

3x=180.0-45.7= 134.3

3x=134.3

x=134.3/3=44.79
