Hi there!

We can use right-triangle trigonometry to solve.

We are given the HYPOTENUSE and ADJACENT sides, so we must use cosine in this instance.

cosθ = Adjacent/Hypotenuse

We can plug in what is given:

cos(28) = A/17

Solve for 'A':

17cos(28) = <u>15.01 ft</u>

Problem #2
marta [7]

Fractions can be converted to decimals and vice versa.

<em>The decimal equivalent  of the fraction of months with 31 days is 0.583</em>

Given:

<em />Total = 12<em> --- months in a year</em>

<em />Months = 7<em> --- months with 31 days</em>

<em />

The fraction (n) of months with 31 days is:

n = \frac{Months}{Total}

So, we have:

n = \frac{7}{12}

The decimal equivalent is:

n = 0.583

Hence, (c) is correct.

Help how do you do this help fast please
GalinKa [24]

Answer:

x= 50°

Hope it helps!

Step-by-step explanation:

The sum of the exterior angles of a polygon is always 360°

So, x+40+x+20+2x+2x = 360

6x + 60= 360

6x = 360-60 = 300

6x= 300

x= 300/6

= 50
