Answer:
4.) Choice B
&
5.) Choice A
Step-by-step explanation:
<em><u>Question 4:</u></em>
First you have to solve for y to get slope intercept form.

The slope is a fraction but you need it to convert it to a decimal so that'll be Choice B.
<em><u>Question 5:</u></em>
For this one I we will use this formula 
I will choose the easy pairs to plug it in 

The slope is a fraction again but you can convert it and that'll be Choice A.
Answer:
820
Step-by-step explanation:
779/x = 95/100
779×100
77,900 ÷ 95
820
Answer:

Step-by-step explanation:
see the attached figure to better understand the problem
we know that
In the right triangle PQR
The sine of angle R is equal to divide the opposite side to angle R (PQ) by the hypotenuse (PR)
so

substitute the values

Find the measure of angle R
using a calculator


Answer:
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Step-by-step explanation:
Given:
Hypotenuse BD = 12 unit
Angle θ = 30°
Find:
Perimeter of rectangle ABCD
Computation:
Using trigonometry function
Sin θ = Perpendicular / Hypotenuse
Sin 30 = CD / BD
0.5 = CD / 12
Length of CD = 6 unit
Cos θ = Base / Hypotenuse
Sin 30 = BC / BD
0.866 = BC / 12
Length of BC = 10.4 unit
Perimeter of rectangle ABCD = 2[Length + Width]
Perimeter of rectangle ABCD = 2[6 + 10.4]
Perimeter of rectangle ABCD = 2[16.4]
Perimeter of rectangle ABCD = 32.8 unit (Approx.)
Answer:
