Answer:
<em>The correct option is: C.
</em>
Step-by-step explanation:
The two angles of the triangle are given as 60° and 60°
As the sum of all three angle in any triangle is always 180°, so the measure of the third angle will be: 180°-(60°+60°) = 180° - 120° = 60°
Now each angle of the triangle is 60°, it means the triangle is equilateral.
The base of the triangle is given as 12. So, the length of each side will be 12.
That means, the value of 
Now in the left right triangle.....

So, the value of 
length = 12 yd
width = 10 yd
height = 12 yd
diagonal = 19.697715603592 yd
total surface area = 768 yd2
lateral surface area = 528 yd2
bottom surface area = 120 yd2
volume = 1440 yd3
ST = 7.2
RT = 4.04
m∠S = 34°
Solution:
Given ΔRST is a right triangle.
RS = 6, ∠T = 56°




1.206 × 6 = ST
7.236 = ST
ST = 7.2




0.674 × 6 = RT
4.044 = RT
RT = 4.04
To find the measure of angle S.
Sum of the interior angles of the triangle = 180°
m∠R + m∠S + m∠T = 180°
90° + m∠S + 56° = 180°
m∠S + 146° = 180°
m∠S = 180° – 146°
m∠S = 34°
It would be A:303.45$ because 357-53.55 which would be 303.45$
Answer:
Step-by-step explanation:
The following points (coordinates) lie on a straight line with slope 3:
(1, 0), (2, 3), (3, 6), (4, 9) ... and so on
So the linear function is y = 3x + b, where b is the y-intercept.
