Answers
Answer:
We will have a new angle [tex]\theta_{new}=143^{\circ}[/tex]
Step-by-step explanation:
If we rotate this angle 90 degrees counterclockwise we just need to add both angles, which means:
[tex]\theta_{new}=44^{\circ} + 99^{\circ}=143^{\circ}[/tex]
Therefore, we will have a new angle [tex]\theta_{new}=143^{\circ}[/tex]

The light blue one -- second from the left.
x = 14 ; y = 7√2
Step-by-step explanation:
This is a right triangle. One of the angles is 45. So is the other base angle.
So one of the legs is 7√2. The other leg is also 7√2 because they are opposite equal angles.
The hypotenuse is
a^2 + b^2 = c^2
a = b
2a^2 = c^2
2 (7√2)² = c^2
2 49 * 2 = c^2
4 * 49 = c^2
c^2 = 196
c = 14

the geometric mean of 2 numbers is 20. one of the numbers 50. what is the other
number?
Answers
Answer:
8
Step-by-step explanation:
Let x = the unknown no.
Then
[tex]\frac{50}{20} = \frac{20}{x}[/tex]
50x = 400
x = 8
If the geometric mean of two numbers is 20, one number is 50 then the other number is 8
What is geometric mean?"The geometric mean is the average rate of return of a set of values calculated using the products of the terms."
Formula to calculate geometric mean is
[tex]GM = \sqrt{x_{1}.x_{2} }[/tex]
Here,
GM = 20
[tex]x_{1}=50\\ x_{2} =?[/tex]
Substitute the values in the formula
[tex]20=\sqrt{50.x_{2} }[/tex]
Squaring on both sides
[tex]400=50(x_{2})\\ x_{2} =\frac{400}{50} \\x_{2}=8[/tex]
Hence, the other number is 8.

Substitution:
X + 2y = 13
-2x - 3y = -18
Answers
Answer:
x = -3
y = 8
Step-by-step explanation:
x + 2y = 13 ------------(I)
x = 13 - 2y -----------(II)
-2x - 3y = -18 ----------(III)
Substitute x = 13 - 2y in equation (III)
-2*(13 - 2y) - 3y = -18
-2*13 - 2y *(-2) -3y = -18
-26 + 4y - 3y = -18 {Combine like terms}
-26 + y = -18 {Add 26 to both sides}
y = -18 + 26
y = 8
Substitute y = 8 in equation (II)
x = 13 - 2*8
= 13 - 16
x = -3
x = -3
y = 8
