Answer: 44 degrees.

Step-by-step explanation: Since the sum of the measures of the angles in a triangle add up to 180 degrees, we can figure out the measure of the third angle by adding the first two angles and subtracting the sum from 180. 102 + 34 = 136. 180 - 136 = 44, so the measure of the third angle is 44 degrees.

I really need this plzzzzzz

Step-by-step explanation:

The exterior angle is the sum of the opposite interior angles of the triangle.

Therefore, m<D +m<C = 118°

=> 8y+3 +3y+5 = 118°

=> 11y = 118° - 8°

=> 11 y = 110°

=> y = 10°

m<D = 8y+3

= 8(10)+3 = 83°

m<C= 3(10)+5 = 35°

m<DEC = 180° -118° = 62°

Perform the addition.<br> (3x² + 3x - 5) + (-7x² + 9)

lakkis [162]

The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
$(3 x^{2} + 3x - 5) + (-7 x^{2} + 9)$ <span>
Use distributive property:
</span> $3 x^{2} + 3x - 5 - 7 x^{2} + 9$
Combine Like Terms:
$
-4 x^{2} +3x+4$
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
