Question

6. If two angles of a
triangle are equal and
other angle is 40. What is
each equal angle?​

Answer 1

Answer:What we need to know before solving

Sum of all internal angles of triangle is 180 degree

Given

Angle 1 and 2 are equal and third angle is 40 degree

To find

Measure of equal angles

Solution

Let the same angles be x each

Then

X+x+40=180.( SUM OF ANGLES OF TRIANGLE)

2x+40=180°

2x=140 °

X= 70°

HENCE 3 ANGLES ARE

70,70,40

Step-by-step explanation:

Answer 2

Answer:

70.

Step-by-step explanation:

Let the base angles be

′

x

′

Therefore,

x+x+40

=180

[Given]

2x=180

−40

2x=140

x=70

Hence,

The base angles of the triangle are 70,70
