The degree measure of angle a is 135°. which expression below is equivalent to the radian measure of angle a?
Kazeer [188]

It is given that \angle a=135^{\circ}.

Now, know that in 180 degrees there are \pi radians. This can be written as:

180^{\circ}=\pi radians

\therefore 1^{\circ}=\frac{\pi}{180} radians (dividing both sides by 180)

Thus, to find the measure of the given angle of 135^{\circ} in radians, we will have to multiply the above equation by 135. Thus, we get:

135^{\circ}=\frac{\pi}{180}\times 135 radians

135^{\circ}\approx2.356 radians

Thus, equivalent to the radian measure of angle a is 2.356

Solve the equation ( 1 point) 3/4x=9<br><br> A) X=12<br> B) X=108<br> C) X=72<br> D) X= 4/9
Elena L [17]

Answer:

x = 12

Step-by-step explanation:

Solve for x:

(3 x)/4 = 9

Multiply both sides of (3 x)/4 = 9 by 4/3:

(4×3 x)/(3×4) = 4/3×9

4/3×3/4 = (4×3)/(3×4):

(4×3)/(3×4) x = 4/3×9

4/3×9 = (4×9)/3:

(4×3 x)/(3×4) = (4×9)/3

(4×3 x)/(3×4) = (3×4)/(3×4)×x = x:

x = (4×9)/3

9/3 = (3×3)/3 = 3:

x = 4×3

4×3 = 12:

Answer:  x = 12
