I need help to solve the problem

natta225 [31]

Since all triangles equal 180 degrees. You will subtract (128 + 23) from 180.

180 - 146 is 34 degrees.

x=34

If B is the midpoint of AC, solve for x, and find the lengths of AB, BC, and AC.

Answer:

49, 49 , 98

Step-by-step explanation:

AC = AB + BC = 2AB

3x - 31 = 2(x+6)
3x - 31 = 2x + 12
3x - 2x = 12 +31
x = 43

AB= BC = x + 6 = 43 + 6 = 49

AC = 2AB = 2* 49 = 98

Help me as soon as possible PLEASE HELP

Answer:

QRT = 47, TRS = 133

Step-by-step explanation:

Since QRS is a line, QRT + TRS = 180.

$QRT+TRS=180\\3x+5+10x-7=180\\$

Then, solve for x. Combine like terms.

$13x-2=180\\13x=182\\x=14$

Then, plug in 14 for x.

$1. (3*14+5)\\\\QRT = 47\\\\2. (10*14-7)\\\\TRS = 133$

sin^8 x - cos^8 x
= (sin^4 x + cos^4 x)(sin^4 x - cos^4 x)
= (sin^4 x + cos^4 x)(sin^2 x - cos^2x)(sin^2 x +cos^2 x)
= (sin^4x + cos^4 x)( sin^2 x- cos^2 x)

Sorry I cant do 4 (d).
