Question

the value of x in given figure is?

pls answers these question
​

Answer 1

Answer:

x + y + z = 180 ------------------eq1

Step-by-step explanation:

where:

y = 180 - 113 =67

z = 45

x = ?

• put in the equation1

x + y + z = 180

x + 67 + 45 = 180

x = 180 - 67 - 45

x = 68

Answer 2

Answer:

Firstly name the triangle as ABC

Angle BAC = 45

Angle ABC = x

Angle ACD = 113

We know that, Angle ACD and ACB are supplementary

So, ACD + ACB = 180

113 + ACB = 180

ACB = 180 - 113

ACB = 67

We know that, sum of all angle of a Triangle is 180

so, angle BAC + ACB + ABC = 180

45 + 67 + ABC = 180

112 + ABC = 180

ABC = 180 - 112

ABC = 68°

So the value of X is 68°
