We will use additional formula:
sin ( 90°+ theta ) = sin 90° * cos(theta) + cos 90° * sin(theta)=
= 1 * cos(theta) + 0 * sin(theta)= cos (theta)           It is proved.

HELP Plssss..... The m
hammer [34]

Answer:

Step-by-step explanation:

Hey there!!!

According to the question,

Angle P is three less than twice less of an angle Q.

Then, let angle Q be x then angle P is 2x-3.

Now, it has also given that they are supplementary angle.

We know that the sum of supplementary angle is 180°.

Therefore, x+ 2x - 3°=180°.

Or, 3x = 180°-3°

Or, x = 177°/3

Therefore the measure of angle Q is 59° and P is 2×59°-3°= 121°.

Hope it helps....

Which is greater? -(-3) or -(3) ? need asap!
Artist 52 [7]
It’s - ( - 3 ) because a negative times a negative equals a positive so it wouldn’t be - ( 3 ) because it would turn into a negative number and - ( - 3 ) would be positive

2(x-3)^2+10=82 solve by isolating x
Leviafan [203]
We have the following equation:
 2 (x-3) ^ 2 + 10 = 82
 We must clear x.
 We pass the constant terms to one side of the equation:
 2 (x-3) ^ 2 = 82 - 10
 2 (x-3) ^ 2 = 72
 (x-3) ^ 2 = 72/2
 (x-3) ^ 2 = 36
 Square root to both members:
 x-3 = +/- root (36)
 x-3 = +/- 6
 The solutions are:
 x1 = 6 + 3 = 9
 x2 = -6 + 3 = -3
 Answer:
 
x1 = 9
 
x2 = -3

Pythagorean theorem is formula we would use:
1.)
c^2=a^2+b^2
c^2=10^2+24^2
c^2=100+576
c^2=676
c= √676
c=26 in

2.)
c^2=7^2+14^2
c^2=49+196
c^2=245
c= √245
c~15.65 cm
