**So, what do u wanna solve?**

**Answer:**

your answers are correct

**Step-by-step explanation:**

A **straight angle** measures 180°. It looks like a straight line with the vertex as a marked point on the line.

__

A **right angle** is usually marked with a little square in the corner, as in diagrams 2 and 5. Diagram 2 also shows **complementary angles**, two angles that have a sum of 90°.

__

**Supplementary angles** have a sum of 180°, so can form a straight angle as in diagram 1.

__

An **obtuse angle** is one that has a measure greater than 90°. (If it is greater than 180°, it is called a *reflex angle*.)

__

An **acute angle** is one that measures less than 90°.

120h -------- 140mAh

120h -------- 0,14Ah

1h -------- 0,14Ah*120

1h -------- 16,8Ah

Answer: 16,8Ah.
