Here is the answer. A minute consists of 60 seconds. Therefore, we can put this in a fraction form as 42/60. Since these are still large numbers, we would simplify this fraction so the answer would be 7/10. Hope this is the answer that you are looking for. Have a great day ahead!

Question 2: Please help I do not understand this question.
Svetradugi [14.3K]

The measurement of AB is 16.23.

Solution:

Given ACB is a right angled triangle.

AC = 10, ∠C = 90° and ∠A = 52°.

cos θ ≈ 0.616

Here AC is the base and AB is Hypotenuse.

To find the length of AB:

$\cos\theta=\frac{\text{Base}}{\text{Hypotenuse}}

$\cos 52^\circ=\frac{10}{AB}

$0.616=\frac{10}{AB}

Do cross multiplication, we get

$AB=\frac{10}{0.616}

AB = 16.23

Hence the measurement of AB is 16.23.

Find the measurement indicated. Round your answers to the nearest tenth. Use Law of Sines​ or Cosines
tatuchka [14]

Answer:

5. 34°

6. 29.7

Step-by-step explanation:

5. Using sine law

25/sin(93) = 14/sin(C)

sin(C) = 0.5592325395

C = 34.00273934°

6. Using cosine law

AC² = 23.2² + 18.1² - 2(23.2)(18.1)cos(91)

AC² = 880.507229

AC = 29.67334206
