Answer: No, because ABC is not a right angle.
Step-by-step explanation: In triangle ABC, the three angles add up to 180
So angle B = 180 - 48 - 47 = 85.
Answer:
y = 9
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° =
sin45° = =
Multiply both sides by y
y × sin45° = 9, that is
y × = 9
Multiply both sides by
y = 9
The answer is B.
The shaded area includes points less than the line, and the slope is negative. Also, the Y intercept is positive 5.
