Find the unknown measures of the indicated angles.

1 answer:

4 0

The angles of a triangle always equal to 180 degrees.

Knowing this, you can solve this by this equation

Angle A + Angle B + Angle C = 180

43 + 85 + Angle C = 180

Angle C = 180 - 43 - 85
Angle C = 52

R=p/4(c+k) for k, please help, thank you!

White raven [17]

Answer:

$k=\frac{-cp+4r}{p}$

Step-by-step explanation:

$r=p/4(c+k)$

$\frac{r}{p/4} =c+k$

$\frac{r}{p/4} -c=k$

$-cp+4r=kp$

$\frac{-cp+4r}{p} =k$

a garage floor measures 150 feet by 120 feet. a scale drawing of the floor on grid paper uses a scale of one unit : 15 feet. wha

Nadya [2.5K]

1 unit = 15 feet

150 feet / 1 unit = 150 / 15 = 10 units

120 feet / 1 unit = 120 / 15 = 8 units

The dimensions of the drawing equates :

10 units by 8 units .

The perimeter of rectangle is 48 cm. Find the sides of the rectangle if one of the sides is 12 cm longer than the other.

natima [27]

L=W+12
2L+2W=48
2(W+12)+2W=48
2W+24+2W=48
4W=48-24
4W=24
W=24/4
W=6 ANS. FOR THE WIDTH.
L=6+12=18 ANS. FOR THE LENGTH.
PROOF:
2*18+2*6=48
36+12=48
48=48

Hope this helps:)
