Answer:
The Sandbox must be 19x19 for the area to be 361.
Step-by-step explanation:
(19x19=361)
Answer:
x ≈ 35.1°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos x = 
= 
, then
x = 
( ) ≈ 35.1° ( to the nearest tenth )
ANSWER: y=4/3x-7
Reasoning: slope is 4/3 (change in y over change in x)
The y intercept is a -7
Then you just fill in the equation
Answer:
The angle is in the first quadrant
Step-by-step explanation:
For angles greate than360°,subtract
360° from the angle until the angle is less than 360°. Hence
405° = 405° - 360°
= 45°
The angle is in the first quadrant. Since the first quadrant can still take as much as 90°
∠R = 100° , ∠S = 40° and ∠T = 40°
<u>Step-by-step explanation:</u>
In a triangle, sum of all the angles in a triangle is equal to 180 degrees.
In Δ RST,
∠R + ∠S + ∠T = 180°
It is given that,
∠S = ∠T
∠R = 2∠S + 20
So plugin these values in the above equation, we will get,
2∠S + 20 + ∠S+ ∠S = 180
4∠S = 180 - 20
∠S = 160/ 4 = 40
∠R = 2× 40 + 20 = 80 + 20 = 100°
∠S = ∠T = 40°
