To find BC:

• we can see that there is a right angle triangle

• to make it easier use the concept

SOH: Sine° = Opposite/ Hypo

CAH: Cos° = Adjacent/ Hypo

TOA: Tan° = Oppo / Adjacent

(look the CAPITAL letter there, it'll helps us later)

So, we are given: 16 (hypo)

we want to find BC : Opposite

WE HAVE (H) and (O) thefore we use SOH

sine 5° = BC/ 16

(then move 16)

sin 5° x 16 = BC

padilas [110]

Answer:

52 cm

Step-by-step explanation:

Use the pythagorean theorem to solve for missing sides in a right triangle.

20²+48²= missing side

20²+48²=2704

Take the square root of 2704 to get the missing side.

$\sqrt{2704 } = 52$

Paula got $10.50 from her grandparents on her birthday. She earned $4.45 by babysitting. How much money is this in all? c HAPPY

Aloiza [94]

We have the following:

To calculate the total money, you have to add the amounts that Paula won, as follows

$\begin{gathered} T=10.5+4.45 \\ T=14.95 \end{gathered}$

Which means that in total they are $ 14.95
