Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

<ADB + <BDC = 180°

IT'S seen that BOTH ADB and BDC are 90 degrees

90+90= 180

PLS HURRY I NEED THE ANSWER FAST
balandron [24]

Answer:

16

notice how a right triangle was formed, and the Pythagorean theorem could be used to solve this :

a^2 + b^2 = c^2

a^2 + 15^2 = 17^2

a^2 + 225 = 289

a^2 = 64

a= 8

multiply it by 2 to get the side of the base

8 * 2 = 16

PLEASE HELP ME!!!
Fynjy0 [20]
<h3>Answer:  15 years old</h3>

=============================================

Explanation:

m = Maggie's age (some positive whole number)

4m = four times her age

4m-7 = seven years younger than 4m = brother's age

Add up her age (m) and her brother's age (4m-7) to get a sum of 68.

m+(4m-7) = 68

5m-7 = 68

5m = 68+7

5m = 75

m = 75/5

m = 15

Maggie is currently 15 years old.

Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.

Their current year ages add to: 15+53 = 68 which confirms the answer.

Hey! How do I write 0.29 (both 2 and 9 are recurring) as a fraction?
Montano1993 [528]
Hi there!

Since a decimal is a portion of 1 we can simply put a 100 in the denominator to form it into a fraction.

By doing this, we get the fraction 29/100.

Since there is no simplifying we can do for the fraction this is it's final form!

Your answer would be 0.29 = 29/100.

Solve equation 3k+45=8k+25
Brrunno [24]

Answer:

k=4

Step-by-step explanation:

First, we can subtract 3k on both sides. It is ultimately easier to start by subtracting the term with a variable. This would result in 45=5k+25. Then, we can subtract 25 on both sides to get closer to isolating k. This becomes 20=5k. We can then divide by 5 on both sides. This means that k=4.
