Help me pls the question is in the picture
MaRussiya [10]

Answer:

M<C = 37 degrees

M<D = 86 degrees

M<DEC = 111 degrees

Step-by-step explanation:

The exterior angle theorem can be measured by the hypotenuse of a 90 degree angle. Since there is no hypotenuse in the matrix, you don't need to make it positive :)

Therefore, after using this theorem, I came to the conclusion that m/C would be 37 degrees, since I calculated the measure of the angle. I used the same tactic on m/D and m/DEC.

I hope this helps :)

a A hole in the shape of a hemisphere is carved into each face of a cube. The holes are identical and centered at the centre of
morpeh [17]

Diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.

<h3>What is a Hemisphere?</h3>

A hemishpere is half of a sphere. Thus, two hemispheres makes one full sphere.

Given the image as shown below, since the identical hemispheral holes are centered at the center of each fce and they touch each other at only one point, it means that two hemisphere meet to make one full sphere.

Therefore, the diameter of a full sphere = side length of cube.

Thus, diameter of each hemispheral holes = the diameter of a full sphere = side length of cube = 2 units.

The label on the car's antifreeze container claims to protect the car between −40°C and 125°C. To covert Celsius temperature to
Solnce55 [7]

Answer:

see below

Step-by-step explanation:

The label on the car's antifreeze container claims to protect the car between -40°C and 125°C.

So inequality which models this situation will be -40°C < T < 125°C

Now we have to show this inequality in Fahrenheit temperature with the help of C=\frac{5}{9} (F-32)

So the compound inequality in Fahrenheit temperature will be

-40 < \frac{5}{9} (F-32) < 125
