Answer:
no! you can label either of the legs a or b. it doesn't matter. the hypotenuse always stays as c though if you're using a formula.
If one angle is 9 times the other angle, and they're complementary, you can set up an equation.
90 = x + 9x
x is the smaller angle. When you solve for x, you get 9.
So, the large angle is 81°, and the smaller angle is 9°.
Hope this helped!! xx
Answer:
units²
Step-by-step explanation:
D and E lie on the x- axis and F is vertically below D
The triangle formed is right at D with legs of length 3 and 7
The area (A) of a right triangle is found using the formula
A = 
bh ( b is the base and h the perpendicular height )
here b = 3 and h = 7, hence
A = × 3 × 7 = units ²
Answer:$50
Step-by-step explanation:
So we have the sweater that’s $30 with a sale of 60% of the original price.
That means $30=60% of the original
So
30=60%start with this
5=10% divide 6 by both sides to get 10%
50=100% times by 10 to get 100%, which is the original price.
So the original price of this sweater is $50
:D
-(x-20)
Basically it’s the same as your other question but your not adding twenty!
