Find the value of the triangle shown below <br> X=

SpyIntel [72]

This is a isosceles triangle. all sides degrees added together (triangle) is equal to 180.

we know one side is 55°, and since its isosceles, it will be congruent on both sides. so there are 2 55°.

since the sum of all angles is 180°, the equation will be 55°+55°+x=180

combine like terms (55+55), which equals to 110.

last, 180-110 = 70

so the answer will be x = 70°

dexar [7]

Answer:

(i) Yes

(ii) Yes

Step-by-step explanation:

We are given that

AB=AC

(i)D is the mid-point of BC

BD=DC

In triangle ADB and triangle ADC

AD=AD

Reason: Reflexive property

BD=DC

Reason:Given

AB=AC

Reason: Given

$\triangle$ ADB $\cong\triangle$ ADC

Reason:SSS postulate

Yes, triangle ADB is congruent to triangle ADC

(ii) Angle B=Angle C

Reason: CPCT

Yes , angle B=angle C
