What is the measure of angle a?

Mkey [24]

Answer:

38°

Step-by-step explanation:

Using the Cosine rule in Δ ABC

cos A = $\frac{b^2+c^2-a^2}{2bc}$

where a, b and c are the sides of the triangle.

Here a = 5, b = 3 and c = 7 , thus

cos A = $\frac{3^2+7^2-5^2}{2(3)(7)}$ = $\frac{9+49-25}{42}$ = $\frac{33}{42}$ , thus

∠ A = $cos^{-1}$ ( $\frac{33}{42}$ ) ≈ 38°

Answer:

y = 50

Step-by-step explanation:

Firstly, let's make an equation. We know that when y is 15, x is 3. Or, in other words, y is 5 times what x is. Therefore we can use the equation, y = 5x.

Now, just plug x into the equation.

y = 5(10)

y = 50

yulyashka [42]

Answer:

Average distance traveled in 15 minutes = 7.5 miles

Step-by-step explanation:

Given function:

$d(t)=0.5t$

where $d$ represents average distance traveled in miles and $t$ represents time in minutes traveled.

To find the average distance traveled in $t=15$ minutes.

Solution:

In order to find the distance traveled in 15 minutes, we will input $t=15$ in the given function.

$d(15)=0.5(15)$

$d(15)=0.5\times 15$

$d(15)=7.5$ miles

Average distance traveled in 15 minutes = 7.5 miles
