Answer:

70° is your measurement for ∠t.

Step-by-step explanation:

Note that a straight line has an angle of 180°

It is given to us that ∠r and ∠t = 180°, and that m∠r = 110°

Plug in 110 for ∠r

110 + ∠t = 180

Isolate ∠t. Note the equal sign, what you do to one side, you do to the other. Subtract 110 from both sides

110 (-110) + ∠t = 180 (-110)

∠t = 180 - 110

∠t = 70

70° is your measurement for ∠t.

Andrei [34K]
We have a right triangle.
Then:
A+B+C=90
Data:
C=90º
A=53º

Therefore:
53º+B+90º=180º
B=180º-53º-90º
B=37º

Answer: B=37º

To check:
Cos 37º=0.79863551...≈0.7986

Darina [25.2K]

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.

Let x be the number of ml you need.

Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg

(1 ml)/(1 mg) = (x ml)/(0.1 mg)

Cross multiply.

1 * x = 1 * 0.1

x = 0.1

Answer: 0.1 ml
