Answer:

m∡B = 55°

AB = 5.2

AC = 7.4

Step-by-step explanation:

m∡B = 180-(90+35)

use Law of Sines to find AB and AC:

sin 90° / 9 = sin 35°/AB

AB = .57(9) = 5.2

sin 90° / 9 = sin 55°/AC

AC = .82(9) = 7.4

Answer:

The measure of Angle B= 55°

AB= 5

AC= $\sqrt{56}$

Step-by-step explanation:

180-35-90 = 55.

$5^{2}$ +56=9

$\sqrt{56}$ = 7.48........

If you were going to make a curtain for a window that was two and a half feet wide and three and a half feet high, what size wou

insens350 [35]

Add 0.5 to each side so you have fabric for the seams and your new numbers are 3 ft and 4 ft

find the area by multiplying 3*4 and get 12 ft

1 yard = 3 feet

12/3= 4 yards

You would need 4 square yards of fabric

Pls help :)) this question is confusing for me :)

Temka [501]

Given:

$y^{2}(2 y-5)-8 y+20$

To find:

The product of the expression.

Solution:

$y^{2}(2 y-5)-8 y+20=y^{2}(2 y-5)+(-8 y+20)$

Take out -4 as a common factor in Last two terms.

$=y^{2}(2 y-5)-4(2 y-5)$

Make sure the terms in both brackets must be same.

Take out common factor (2y - 5) from both terms.

$=(2 y-5)(y^{2}-4)$

4 can be written as 2².

$=(2 y-5)\left(y^{2}-2^2\right)$

Using the identity: $(a^2-b^2)=(a-b)(a+b)$

$=(2 y-5)(y-2)(y+2)$ .

The product is $(2 y-5)(y-2)(y+2)$ .
