Answer:
Firstly, notice the relationship the two triangles have. They have conjoining ends that form vertical angles (looks like a middle x). Vertical angles are equivalent in measure of degrees.
Secondly, notice that the triangle on the right side is a right triangle. One of its angle's measurements are also given; 40 degrees. If you know that the sum of a triangle's angles equal 180 degrees, then simply subtract the known angles measurements from 180.
180-(90+40)= 180-130=50.
Therefore, the vertical angles measurement is equivalent to 50 degrees.
Apply the principle of the sum of all angles in a triangle equivalent to 180 degrees to the left triangle, and you will be able to find the measurement of the "?" angle.
180-(50+25)= 180-75=105
SO HERE IS YOUR ANSWER= 105 degrees is the value of the angle marked with a "?"
I hope you are having a great day too;)!
Solve your equation step-by-step.
x^2+5=41
Subtract 5 from both sides.
x^2+5−5=41−5
x^2=36
Take square root.
x=±√36
x=6
or
x=−6
So your answer suppose to be C and D.
But if you were to put only one answer in the answering box, then just say C)
Answer: 3/2
Step by step:
3/4 + 4y/3
3/4 + 4y/3 = 4y/3 + 3/4
y= 1 1/2 = 3/2
answer:
I think that the right answer is the first, because:
- 6 + 1.5r = - 12
+ 1.5r = -12 + 6
1.5/1.5 = - 6
r = - 6
