Answer:
(-A)^2 for A = 5
(-5)^2
=25
Step-by-step explanation:
first, replace A by 5, and maintain the negative to the 5.
multiply (-5)^2.
nb: don't forget to maintain the bracket when multiplying. if you maintain the bracket, you'll get a positive number, but if you don't, you'll get a negative number.
In 5xy it would be 5x×1y and then 2y if they variable doesn't have a number infront of it it is assumed to be a One.
Answer:
8
Step-by-step explanation:
Absolute Value (| |) is the number of spaces away from 0. -8 is 8 spaces away from 0 and 8 is 8 spaces away from 0.
Hope this helps plz mark brainliest if correct :D
Answer:
What are your answer choices?
Using the sine law of triangles to solve for angle C:
b / sin B = c / sin C
C = arcsin (c * sin B / b)
C = 30.7<span>°
Since interior angles of a triangle always add up to 180</span><span>°, we can use this to solve for angle A:
angle A = 180</span>° - 73° - 30.7<span>°
angle A = 76.3</span><span>°
Having solved for angle A, we can solve for side a using the sine law.
a / sin A = b / sin B
a = b * sin A / sin B
a = 15.2
Therefore, the correct answer is B.</span>
