An angle measures 94" more than the measure of its supplementary angle. What is the
PIT_PIT [208]

Answer:

The measure of the angles are 137 and 43

Step-by-step explanation:

Firstly, we need to understand what is meant by saying two angles are supplementary.Two angles are termed supplementary if the addition of the value of both angles equal 180.

Now let the two angles we are seeking in this question be x and y respectively

We write our first equation using the supplementary information;

x + y = 180 •••••••••••(i)

Secondly we are made to know that the difference between these angles is 94

Mathematically;

x - y = 94

or simply x = 94 + y; insert this into equation 1 above

94 + y + y = 180

2y = 180 - 94

2y = 86

y = 86/2

y = 43

x = 94 + y = 94 + 43 = 137

Lara found the volume of a sphere with a diameter of 10.
Paraphin [41]

Answer:

No, she used the diameter instead of the radius measure.

Step-by-step explanation:

we know that

The volume of the sphere is equal to

V=\frac{4}{3}\pi r^{3}

we have

r=10/2=5\ units ----> the radius is half the diameter

substitute

V=\frac{4}{3}\pi (5)^{3}

V=\frac{500}{3}\pi\ units^{3}
