Answer:
175
Step-by-step explanation:
The circle has to = 360 degrees. 360-10=350
350/2=175
The x is halfway that's why you divide by 2.
Step-by-step explanation:
For 4.
4b + 2b + 3b = 180°< Sum of angles of triangle >
9b = 180°
b = 180° / 9
b = 20°
4b = 4* 20° = 80°
2b = 2* 20° = 40°
3b = 3 * 20° = 60°
For 5.
x = 64° + 45° <Exterior angle of a triangle is equal to the sum of two opposite interior angles>
x = 109°

Answer:

Step-by-step explanation:
So we want to make x the subject of the formula:

First, distribute the left side:

Combine all the terms with x with it on one side. To do this, first subtract bx from both sides. The right side cancels:

Remove the -ab from the left. Add ab to both sides. The left side cancels:

Now, distribute out the x from the left side:

Divide both sides by (a-b). The left side cancels:

Therefore:

The second one and the third one have a product of 3/4 hope this helps you
