Hi the answer to ur question is a:BTW I stuck to LOLOL
Answer:
40
Step-by-step explanation:
In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.
Lets find Angle 2 first.
First of all, the angle between angle 40 and 90 can be found easily.
That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:
40 + x + 90 = 180
Lets solve for "x":
40 + x + 90 = 180
130 + x = 180
x = 180 - 130
x = 50
Now, This angle (50) and Angle 2 are same [vertical angles]
So,
Angle 2 = 50
Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:
90 + Angle 1 + Angle 2 = 180
90 + Angle 1 + 50 = 180
Angle 1 + 140 = 180
Angle 1 = 180 - 140
<u>Angle 1 = 40</u>
Answer:
47-Step-by-step explanation:
X=121 because they are vertical angles
48- first divide 96 by 6 together the surface area of each side which is equal 16 then to find the length and the width find the square root of 16 which is 4 because it is a cube the length/width/height are all equal to four. So do 4 x 4 x 4 to find the volume of one cube. Which is equal to 64 then multiple by 8 to get the total volume 512cm^3
First combine like terms in parentheses. 4x-5x = -1x. Now -1x - 5y should be in the parentheses. Now use the distributive property and multiply both of those terms by 2. The product is -2x -10y so the answer is B.
