Answer:

41.4°

Step-by-step explanation:

Reference angle = θ

Hypotenuse = 8

Adjacent = 6

Therefore,

$cos(\theta) = \frac{adj}{hyp}$

$cos(\theta) = \frac{6}{8}$

$cos(\theta) = 0.75$

$\theta = cos^{-1}(0.75)$

$\theta = 41.4 degrees$ (nearest tenth)

Hey there! Welcome to Brainly! I'm happy to help you!

When we are talking about the height and base, let's use the variables h and b. With the information we have been given, we can make the following equations below.

h=10 (the height is 10)

b=h/2 (base is half as long as the height)

We see that h is equal to ten. b is equal to h divided by two, so it is therefore ten divided by 2! We take the value for h and the plug it into the second equation!

b=10/2

b=5

So, we now know that the height is 10 cm and that the base is 5 cm. However, we need to find the area. To find the area of a rectangle, we just multiply the base by the height!

10(5)=50

Therefore, the area of the sticker is 50 cm².

I hope that this helps! Have a wonderful day!
