30 degree

The sum of isosceles triangle is 180 degree. And this triangle 2 sides have to be equal.
So one of our angle is 120 degree. Two angle will be 180-120 = 60 degree

Now one angle 60/2=30

the measure of an exterior angle of triangle is 84 degrees. the measure of one of its remote interior angles is 22 degrees. what
Ksju [112]

Answer:

62° and 96°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 remote interior angles.

Let x be the other remote interior angle, then

22 + x = 84 ( subtract 22 from both sides )

x = 62

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 known angles from 180 for third angle

third angle = 180 - (62 + 22) = 180 - 84 = 96

The other 2 interior angles are 62° and 96°

10x + 8y = -6<br> -2x − 8y = -18
hjlf

Answer:

(-3,3)

Step-by-step explanation:

10x + 8y = -6

-2x − 8y = -18

Add these two equations together to eliminate y

10x + 8y = -6

-2x − 8y = -18

------------------------

8x = -24

Divide each side by 8

8x/8 = -24/8

x = -3

Now we need to find y

10x + 8y = -6

Substitute x =-3

10 (-3) + 8y = -6

-30 +8y = -6

Add 30 to each side

-30+30 +8y = -6+30

8y = 24

Divide by 8

8y/8 = 24/8

y =3

(-3,3)
