Question

In the following triangles, find the value of x :
Р
70°
x
Q
R​

Answer 1

Answer:

40 degree

Step-by-step explanation:

if the triangle is iscocles triangle

p=70degree

p=R(opposite angles of iscocles triangle are equal)

R=70degree

P+R+Q=180degree

Q=180-140

Q=40 DEGREE

Answer 2

Answer:

In ΔABC,

∠ACD = ∠A + ∠B (Exterior angle property)

= 70∘ + 40∘

= 110∘

Hence, the measure of ∠ACD is 110∘.
