(5x + 10)2 - (4x + 3)
(10x + 20) - (4x + 3)
6x + 17
Answer:
Since we have the information for Angles 1 and 3, and they are vertical, we can set them equal to each other. Once we have done this we can find the measures of them combined, and subtract it from 360 in order to only have the measure of 2 and its vertical angle. Finally, all we need to do now is divide the remaining measure by 2, and this will give us the measure of angle 2.
Angle 1=Angle 3
4x+30=2x+48
2x+30=48
2x=18
x=9
Angle 1=4(9)+30
Angle 1=36+30
Angle 1=66
Angle 1=Angle 3
Angle 1+ Angle 3=132
360-132=228
228/2=114
Angle 2= 114
Answer:
Step-by-step explanation:
We need to apply the following identity:
Then, applying this, you know that for :
We need to remember that:
and
Therefore, we need to substitute these values into .
Then, you get:
Answer:
a = 40 degrees
Step-by-step explanation:
the inscribed angle of 200 degree arc is 100 degrees.
the sum of all the interior angles of a triangle is 180 degrees so:
angle a = 180 - 100 - 40 = 40 degrees
Answer:
It is -22.3
Step-by-step explanation:
Since it is subtraction, the answer must be smaller than -13.4. -4.5 is bigger than -13.4 so it is incorrect. The answer is -22.3
