You have to find the measure of angle QPR.

Solve:

$40 = 8x + 7 + 9x + 16$

Add like terms

$40 = 17x + 23$

Solve

$40 - 23 = 17x + 23 - 23$

$17 = 17x\\\frac{17}{17} = \frac{17}{17}x\\1 = x$

Plug in x to solve for the angle measure of QPR

$9(1) + 16 =\\9 + 16 =\\25$

The angle measure of QPR is 25°

Show that cos 30 degree + sin 60 degree / 1+ sin 30 degree + cos 60 degree is equal to cos 30 degree

Soloha48 [4]

Answer:

cos 30

Step-by-step explanation:

cos 30 + sin 60 / 1+ sin 30 + cos 60

= root3 / 2 + root3/2 / 1 + 1/2 + 1/2

= root 6/2 by 4/2

= root 6/4

= root 3/2

= cos 30

Two triangular pyramids are similar the volume of the large pyramids is 729cm and the volume of the smaller pyramids is 64 cm .

lilavasa [31]

Answer:

18 cm for larger base

Step-by-step explanation:

For similar figures, there is a formula regarding volume, area, and length

Large: small = y: x for length

large: small = (y^3) / (x^3) for volume

729 cm cube/ 64 cm cube = large : small

9: 4 = large: small by length

large/ 8cm = 9/ 4

large = 8*(9/4) = 2*9 = 18 cm
