Answer:

C

Step-by-step explanation:

If Ricardo started studying at 4 p.m and for sure will not stop until after 7 p.m, that means that he will be studying for 3 hours at least, and maybe even longer. So the time he will spend studying is at least 3 hours.

Therefore, x>3, where x is the time Ricardo will spend studying.

I’ve been stuck can someone explain
MariettaO [177]

Answer:

Option (3)

Step-by-step explanation:

From the figure attached,

AB and CD are two chords intersecting at O.

m∠AOD = 37°

m∠AOC + m∠AOD = 180° [Since these angles are supplementary angles]

m∠AOC = 180° - 37°

              = 143°

By the theorem of intersecting chords,

Measure of angle formed is the half of the sum of measures of the arcs intercepted by the angle and vertical angle.

m∠AOC = \frac{1}{2}(\widehat{AC}+\widehat{BD})

143° = \frac{1}{2}[(x+5)+(x-5)]

143° = x

Therefore, Option (3) will be the answer.

In the isosceles trapezoid below,<br> X =<br> 5x+ 15°<br> 7x-11°
tangare [24]

Answer:

x = 13°

Step-by-step explanation:

5x+15°=7x-11°

5x-7x = -11°-15°

-2x = -26° divide both sides by -2

x = 13°

5x+15° = 5×13°+15° = 80°

7x-11° = 7×13° -11°. = 80°
