Question

please help in these questions we have to find the x
and please if you don't know please don't answer...! ​

Answer 1

Answer:

120

Step-by-step explanation:

CAB=30=ACB because AB=BC

CAB+ACB+ABC=180

30+30+ABC=180

ABC=120

X=120

Answer 2

Answer:

x=120⁰

angle DAC + angle CAB = 180⁰.....linear pair

150⁰ + angle CAB = 180⁰

angle CAB = 180-150

= 30⁰

Given AB= BC

so ABC is an isosceles triangle

angle A = angle C

angle B = 30⁰

We know that sum of interior angle of triangle is equal to 180⁰

So, angle A + angle B+ angle C = 180⁰

30⁰ + angle B + 30⁰ = 180⁰

60⁰ + angle B + 30⁰ = 180⁰

angle B = 180 - 60

= 120⁰

Therefore, the value of x is 120⁰
