# A right triangle has one side that measures 4 in. The angle opposite that side measures 80o. What is the length of the hypotenus

e of the triangle? Round to the nearest tenth.

A: 3.9 in.

B: 4.1 in.

C: 22.7 in.

D: 23.0 in.

2 answers:

In order to find the length of the hypotenuse, we use knowledge on trigonometric functions which would be sine and is expressed as:

sine (theta) = opposite side / hypotenuse

sine 80 = 4 / hypotenuse

Hypotenuse = 4.1 in <---- OPTION B

**Answer:**

**Step-by-step explanation:**

Move the decimal point eight places to the left.

16 or 4^2

This is really saying is 1/(1/4^2)

A cross because they are intersecting each other at the center of each line.

**Answer:**

1,665.25 km

**Step-by-step explanation:**

Use the point slope equation: y - y1 = m(x - x1)

(-1, -3); m = 4

Plug these numbers in.

y - (-3) = 4(x - -1)

y + 3 = 4x + 4

**y = 4x + 1**
