ASNWER CORRECTLY AND YOU WILL GET 40 POINTS ALONG WITH BRAINLIEST
FromTheMoon [43]

Answer:

60

Step-by-step explanation:

What we know:

  • ABD is a straight angle, it measures 180 degrees
  • Angle CBA + CBD = 180 degrees
  • Angle GFH = CBA (they are alternate exterior angles)

Equation:

GFH + CBD = 180

Substitute:

3x + 6x = 180

Add:

3x + 6x = 180

9x = 180

Divide:

9x = 180

/9     /9

x = 20

Substitute:

GFH = 3x

GFH = 3(20)

GFH = 60

m<GFH is 60°

The three angles of a triangle measure x+37, 90, and x+67. Find the measurement of the smallest angle in degrees.
vichka [17]

Answer:

The first angle is the smallest

Step-by-step explanation:

Step one:

given data

Angle 1= x+37

Angle 2= 90

angle 3= x+67

We know that the sum of angle in a triangle is 180

so

x+3+90+x+67= 180

collect like terms

2x+160= 180

2x=180-160

2x= 20

divide both sides by 2

x= 10

Step two:

so

Angle 1= 10+37= 47 °

Angle 2= 90= 90

angle 3= 10+67= 77 °

Harriet has 3/4 tank of gas left in her car. if she needs 1/4 tank to go to her friends house and another 1/4 tank to get back h
KATRIN_1 [288]
Yes she does have enough. Here is why: If you add 1/4 and 1/4, you get 2/8 which is also 1/2. 3/4 is bigger than one half. If you subtract 1/2 from 3/4, you get 1/4. So she would have 1/4 left. Absolutely enough to get to her friends house and back. :)
