Answer:

A. 55°

Step-by-step explanation:

Complementary angles are angles that add up to give us 90°.

Since <A and <B are complementary angles, it implies that:

m<A + m<B = 90°

If m<A = 35°, therefore:

35° + m<B = 90°

Subtract 35° from each side

m<B = 90° - 35°

m<B = 55°

ABC is a right triangle. If AC = 12 and BC = 13, find AB.

AysviL [449]

Since BC is the hypotenuse...

α = 12
c = 13

Hence..

13² = 12² + ß²
ß = √(13² - 12²)
= √(169 - 144)
= √25
= 5

Hence, AB = 5

I hope this helps!

frutty [35]

Answer:

Calculus

Step-by-step explanation:

Calculus: z = (94-70)/12 = 2

Bio: z = (74.5-77)/10 = -0.25

History: z = (45-53)/16 = -0.5

Physics: (70.5-60)/14 = 0.75

Answer:

x = $\frac{7}{5}$

Step-by-step explanation:

To solve for x, we need to isolate it [get it alone on one side]

We should start by simplifying (combining the like-terms of our equation):

5 + 5 = 5x + 5 - 2

10 = 5x + 3

- 3 - 3 (subtract 3 from both sides to isolate x)

7 = 5x

÷5 ÷5 (divide both sides by 5 to find "1"x)

$\frac{7}{5}=x$

So, x = $\frac{7}{5}$

(x = 7/5)

hope this helps!!
