Answer:
10°, 80°
Step-by-step explanation:
Setup
Let x and y represent the measures of the two acute angles in the right triangle.
From your knowledge of right triangles, you know the two acute angles are complementary:
x + y = 90
The problem statement gives you another relation:
x = 2(y + 30) . . . . twice the sum ...
__
Solution
The second equation gives you an expression for x that can be substituted into the first equation.
(2(y +30)) + y = 90
3y +60 = 90 . . . . . . . . collect terms
3y = 30 . . . . . . . . . subtract 60
y = 10 . . . . . . . . divide by 3
x = 2(y +30) = 2(40) = 80
The two angles are 10° and 80°.
What slope is perpendicular to m= 5/8
m=-5/8
m=5/8
m=-8/5
m=8/5
Answers
Answer:
C) [tex]m =\frac{-8}{5}[/tex]
The slope of the perpendicular line [tex]m =\frac{-8}{5}[/tex]
Step-by-step explanation:
Explanation:-
Given that the slope of the given line is
[tex]m =\frac{5}{8}[/tex]
The slope of the perpendicular line
= [tex]\frac{-1}{m}[/tex]
The slope of the perpendicular line
= [tex]\frac{-1}{\frac{5}{8} }[/tex]
Final answer
The slope of the perpendicular line
[tex]m =\frac{-8}{5}[/tex]
which of the following equations is an example inverse variation between the variables X and Y?
A.
[tex]y = \frac{x}{8} [/tex]
B.
[tex]y = \frac{8}{x} [/tex]
C.

Pedro is getting balloons for his grandmother's birthday party. He wants each balloon string to be 12 feet long. At the party store, string is sold by the yard. If Pedro wants to get 52 balloons, how many yards of string will he need? 1 foot = 1 3 yard
Answers
Answer:
Total length of string required in yards [tex]8112[/tex] yards
Step-by-step explanation:
The length of the string attached with each balloon is equal to [tex]12[/tex] feet
In the party total number of balloon used is equal to [tex]52[/tex] balloons
The total length of the string required
Length of string used in one balloon * total number of balloons
[tex]= 12 * 52 = 624[/tex] feet
1 feet is equal to 13 yards
Total length of string required in yards [tex]13 * 624 = 8112[/tex] yards
