Answer:
71.8° F
Step-by-step explanation:
Given 75° and 4 times 0.8° drop = 3.2°, so the temperature is 75° - 3.2°
= 71.8° F
0.15x + 100
x representing amount of text messages sent or received
Answer:
So find the what?
Step-by-step explanation:
The only way you can find x here is to use a trig ratio. We have the reference angle of 75, CA is 10 which is the side adjacent to the reference angle, and we are looking for the hypotenuse. The ratio that relates the side adjacent to a reference angle to the hypotenuse is cosine. Therefore,
. Solving for x we get
. Do that on your calculator and find that the hypotenuse is 38.6 m long, last choice from above.
Answer:
<u>The correct answer is C. 129.</u>
Step-by-step explanation:
Let's recall that the Inscribed Quadrilateral Theorem states that a quadrilateral is inscribed in a circle if and only if the opposite angles are supplementary.
In the case of the inscribed quadrilateral ABCD in the graph attached, we have that:
m∠C= 51°, therefore its supplementary angle, ∠A, should be the difference between 180° and m∠C.
m∠C= 180° - m∠A
Replacing with the real values:
51 = 180 - m∠A
m∠A = 129°
<u>The correct answer is C. 129.</u>
