Answer:

20

Step-by-step explanation:

3 (b + a) = c

3 (4 + 5) = 7

12 + 15 = 7

27 = 7

27 - 7

\huge\boxed{ \sf{Answer}}

Given,

a = 5 \\ b = 4 \\ c = 7

And the equation we need to solve is,

3(b + a) = c

To find the answer, you need to substitute the values of a, b & c in the equation.

3(b + a) = c \\  3b + 3a = c \\  ( 3 \times 4) +( 3 \times 5) = 7 \\   12 + 15 = 7 \\ 12 + 15 - 7 = 0 \\  = 27 - 7 \\  = 20

↦ The answer is <u>2</u><u>0</u><u>.</u>

Find the measurement of E<br> •56<br> •132<br> •51<br> •63
Burka [1]

Answer:

∠ E = 56°

Step-by-step explanation:

the external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ MGF is an exterior angle of the triangle , then

10x + 12 = 5x - 4 + 76

10x + 12 = 5x + 72 ( subtract 5x from both sides )

5x + 12 = 72 ( subtract 12 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

Then

∠ E = 5x - 4 = 5(12) - 4 = 60 - 4 = 56°

Solve the right triangle. Will give points!
Anna [14]

Answer:

  • EF = 4.1
  • DE = 9.1
  • m∠F = 66°

Step-by-step explanation:

The hypotenuse and one acute angle are given. The relevant relations are ...

  Sin = Opposite/Hypotenuse

  Cos = Adjacent/Hypotenuse

__

For the given triangle, these tell us ...

  sin(24°) = EF/DF = EF/10

  EF = 10·sin(24°) ≈ 4.1

and ...

  cos(24°) = DE/DF = DE/10

  DE = 10·cos(24°) ≈ 9.1

The remaining acute angle is the complement of the given one:

  F = 90° -D = 90° -24°

  ∠F = 66°
