Answer:

x ≈ 57.8°

Step-by-step explanation:

The relevant trig relation is the one that relates the side adjacent to the angle to the hypotenuse and the angle:

Cos = Adjacent/Hypotenuse

cos(x) = 8/15

The value of x is found using the inverse cosine function:

x = arccos(8/15)

x ≈ 57.8°

Hello,

Let's assume f the age of the father,
s the age of the son.

<span>The age of a father is 2 less than 7 times the age of his son ==> f=7s-2 (1)

</span>
<span>In 3 years, the sum of their ages will be 52 ==>(f+3)+(s+3)=52 (2)

(2)==>f+s+6=52
==>f+s=46 (3)
(3) and (1) ==>7s-2+s=46
==>8s=48
==>s=6
f=46-6=40

Answer:

$C = 28.9$

Step-by-step explanation:

Given the right angled triangle, ∆BCD, you are required to find the measure of angle C.

Apply the trigonometric ratio formula to find m < C.

Adjacent side = 7

Hypotenuse = 8

Trigonometric ratio formula to apply would be:

$cos(C) = \frac{7}{8}$

$cos(C) = 0.875$

$C = cos^{-1}(0.875)$

$C = 28.9$

Cynthia completed 2\3 of her to do list in the morning and finished 1\8 of the items during lunch yet lunch break what traction

il63 [147K]

Answer:

Step-by-step explanation:

Alright, lets get started.

In the morning Cynthia completed the work = $\frac{2}{3}$

During her lunch break, she completed = $\frac{1}{8}$

So, she completed total of her work : $\frac{2}{3}+\frac{1}{8}$

So, we need to add these two fractions.

First making common denominator , so

$\frac{16}{24}+\frac{3}{24}$

So, adding = $\frac{19}{24}$

It means she had finished $\frac{19}{24}$ fraction of het to do list. : Answer

Hope it will help :)
