Answer:

Vertical angles = 81 degrees

Angle (4y-1) = 99 degrees

Linear pair = 81 + 99 = 180 degrees

Step-by-step explanation:

2x + 5 = 3x - 33 (vertical angles)

33+5 = 3x - 2x

38 = x

3(38) - 33 = 81 degrees

4y - 1 + 81 = 180 (linear pair angles)

4y = 180 - 80

y = 100/4

y = 25

4(25) -1 = 99 degrees

Need help with this geometry

Rasek [7]

Answer:

y = 2

Step-by-step explanation:

The mid segment HJ is half of the third side GK , that is

HJ = $\frac{1}{2}$ GK , substitute values

2y = $\frac{1}{2}$ (y + 6) ← multiply both sides by 2 to clear the fraction

4y = y + 6 ( subtract y from both sides )

3y = 6 ( divide both sides by 3 )

y = 2

What are the possible values of x if (4c-5)^2= 49?

kykrilka [37]

Answer:

c = 3 c = -1/2

Step-by-step explanation:

(4c-5)^2= 49

Take the square root of each side

sqrt((4c-5)^2)= ±qrt(49)

4c-5 = ±7

Separate into two equations

4c-5 = 7 4c-5 = -7

Add 5 to each side

4c-5+5 = 7+5 4c-5+5 =-7+5

4c =12 4c = -2

Divide by 4

4c/4 = 12/4 4c/4 = -2/4

c = 3 c = -1/2

maria [59]

Answer:

$1,125\ ft^{2}$

Step-by-step explanation:

we know that

The surface area of the triangular prism that will be covered with insulation is equal to the area of the two triangular faces plus the two lateral rectangular faces

$SA=2[\frac{1}{2}(15)(15)]+2[(30)(15)]= 1,125\ ft^{2}$
