Question 11
x+x+1/2x+1/2x=360
x+x+2/2x+=360
x+x+x=360
3x=360
x=120
Then substitute 120 in the place of x
x1=120
x2=120
1/2(120)=60
1/2(120)=60
To check your answer you can add 60+60+120+120 the should be equal to 360
Question 12
x+x+(x-45)+(x-45)+(x-45)=540
x+x+x-45+x-45+x-45=540
5x-135=540
5x=540+135
5x=675
x=675/5
x=135
Then substitute 135 in the place of x
x1=135
x2=135
135-45=90
135-45=90
135-45=90
To check your answer you can add 135+135+90+90-90 the should be equal to 540

Answer:
A≈50.27
Step-by-step explanation:
The formula for an Area of a circle is: A=πr(squared)
As was can the the diametter is 4, and the radius is half of the diameter, making the radius half of 4 whitch is 2. now just plug in two for R.
A= π4(squared)
4(squared) = 16
A= 16π
A= 50.27
Answer:
16.2
Step-by-step explanation:
Since, if the sum of two angles is 90° then they are called complementary angles.
Here, the given angle is 73.8°,
Let x be the complementary angle of 73.8°,
Thus by the above definition,
x + 73.8° = 90°,
By subtraction property of equality,
⇒ x = 16.2°,
Hence, the complementary angle of 73.8° is 16.2°.

Answer:
x = 14
Step-by-step explanation:
4x - 4 + 4x - 4 + x = 118
9x - 8 = 118
9x = 126
x = 14
