Question

Two angles of a triangle are equal and the third angle measures 70°. Find the measure of each of the unknown angles.

STEP BY STEP EXPLANATION. ​

Answer 1

Answer:

55°, 55°, 70°

Step-by-step explanation:

sum of all angles of triangle is 180°

two angles of triangle are equal.

let measure of one of them angle be x.

x + x + 70° = 180°

2x +70° = 180°

2x = 180°-70°

2x = 110°

x = 110/2

x = 55°

so measures of angles of triangle are 55°, 55° and 70°

Answer:

Angles are 55

Step-by-step explanation:

Consider ∆ABC

Given:

Two angles are equal

let,

$< a = < b$

Let

$< a \: and \: < b \: be \: x$

Let

$< c = 70$

Using Angle Sum Property:

$< a + < b + < c = 180$

$x + x + 70 = 180 \\ 2x = 180 - 70 \\ x = \frac{110}{2} \\ x = 55$

The unknown angles are 55

Hope this helps....
