Answer:

  70.9°

Step-by-step explanation:

The relationships between trig functions and sides of a right triangle are summarized in the mnemonic SOH CAH TOA. In this triangle, you have the side Adjacent to the angle  (48), and the side Opposite to the angle (139). The mnemonic reminds you that an appropriate trig function for the angle is ...

  Tan = Opposite/Adjacent

  tan(?) = 139/48

Then the angle can be found using the inverse tangent function:

  ? = arctan(139/48) ≈ 70.9°

The angle measure is about 70.9°.

An adult blinks about 450 times in 30 minutes. A 12 year old blinks 150 times in 15 minutes. How many more times does an adult b
liq [111]
One way to figure this out is  to you can set up two equivalent fraction problems to figure out in both cases how many times the adult and twelve year old each blink in 60 minutes.

Adult blinks: \frac{450}{30}  =  \frac{?}{60}

Child blinks: \frac{150}{15}  =  \frac{?}{60}

In the "adult blinks" problem, you know that 30 is half of 60 - you can then multiply the numerator 450 x 2 to get 900 blinks per 60 min.

In the "child blinks" problem, 15 is one-quarter of 60, so you can multiply the numerator 150 x 4 to get 600 blinks per 60 min.

You can then just subtract the two new numerators, 900 - 600, to find that the adult blinks 300 more times than the 12-year-old in 60 minutes.
