Question

find the value of X and unknown n.o​

Answer 1

Answer:

x+6+4x-3+5x+7=180

so the value of x is 17

by this we can find corresponding angles

by putting the value of x

Answer 2

Answer:

x=8, 4x-3=32-3=29, 5x+7=40+7=47

Step-by-step explanation:

Given that,

The angle given is 90°

So,

x+6+4x-3+5x+7=90

10x+10=90

10x=90-10

10x=80

x=80÷10

x=8

Therefore,

x=8

4x-3=(4×8)-3

=32-3

=29

5x+7=(5×8)+7

=40+7

=47
