4) c = 38

5) x = 50

Step-by-step explanation:

4) The marked angles are a "linear pair", meaning their total is 180°:

3c° +(2c -10)° = 180°

5c = 190 . . . . . . . divide by °, add 10, collect terms

c = 38 . . . . . . . . . divide by 5

__

5) The interior angle at C brings the total of the marked angle and the interior angle to 360°

330° + (interior angle) = 360°

(interior angle) = 30° . . . . . . . . . subtract 330°

The interior angles of the triangle total 180°, so we have ...

x° +2x° +30° = 180°

3x = 150 . . . . . . . . . . . . . divide by °, subtract 30

x = 50 . . . . . . . . . divide by 3

A

Step-by-step explanation:

7*3.14^2 = 44

C = 38, x = 50

Step-by-step explanation:

4. All the angles must be equal to 180.

Hence.

3c + 2c - 10 =180

5c - 10= 180

5c = 190

C = 38

5. First solve for angle c = 360- 330 = 30

The internal angles of a triangle is 180.

Hence.

x + 2x + 30 = 180

3x = 150

x = 50

hi dont report me we are friends can i get brainliest plzz?

Step-by-step explanation:

For #4 - c=38

38x3=114 and 38x2-10=66. 114+66=180

For #5 - x=50

180=30+3x

(subtract 30 from both)

150=3x

(divide by 3)

50=x

44 because 3.14*(7^2) is 44

point

Step-by-step explanation:

B,C,B

Explanation:

Step-by-step explanation:

Question 1:

All triangles have a sum of 180°.

180 - (56 + 39)

180 - 95 = 85

So, now that you know the measurement of the third angle of the triangle, you can find the missing exterior angle. Exterior angles and interior angles that are side-by-side are supplementary angles meaning that have a sum of 180°. So, you would subtract 85 from 180 which is 95.

So, the measurement of the missing angle is 95°.

Question 2:

All triangles have a sum of 180°.

we already know the angle of ∠1 and since the triangle is an isosceles triangle, then both of the base angles have a measurement of 67°. Now, we find the value of x.

180 - (67 + 67)

180 - 134 = 46

3x - 14 = 46

3x = 60

x = 20

So, the value of x is 20.

Substitution property of equality

Step-by-step explanation:

Because you substituted the value of y in the equation 🙂

Hope this helps!
