Answer:

x = \sqrt{12} = 3.464

Step-by-step explanation:

AC=AD+DC=13\\\text{Because ABC is a right triangle then}\\AB^2=AD.AC\\\Rightarrow AB^2=1 \times 13=13\\\Rightarrow AB = \sqrt{13}\\\text{In the right triangle ABD, since Pythagoras we also have}\\AB^2=AD^2+BD^2\\\Rightarrow BD^2=AB^2-AD^2\\\Rightarrow x^2= 13 - 1=12\\\Rightarrow x = \sqrt{12} = 3.464.

One supplementary angle is 15 degrees less than twice the other. Find the measure of the two supplementary angles.
Scilla [17]

Answer:

The measure of the two supplementary angles are 65 degrees and 115 degrees.

Step-by-step explanation:

The sum of supplementary angles is equal to 180 degrees. Let x and y are two angles such that,

x+y=180\ ....(1)

According to given condition,

One supplementary angle is 15 degrees less than twice the other, it means,

x=2y-15\ .....(2)

Putting the value of x from above equation in equation (1),

2y-15+y=180\\\\3y-15=180\\\\3y=195\\\\y=\dfrac{195}{3}\\\\y=65^{\circ}

Now put the value of y in equation (1), so,

x+65=180\\\\x=115^{\circ}

So, the measure of the two supplementary angles are 65 degrees and 115 degrees.

Answer plz if you put a not so nice or relevent answer i will do the same
gladu [14]

Answer:

1. A 2.D

Step-by-step explanation:

G is the number of girls who attended so that will be our product.

Since 75% of the girls attended the dinner and there are 12 girls on the team we are trying to find a part of the team that attended the dinner so

we would multiply a decimal times the whole.

Convert 75% into a decimal

\frac{75}{100}  = 0.75

Multiply that by 12 to equal G

0.75(12) = g

So the answer is A

Kim pick 2 1/3 lbs every 1/4 hour. We are asked how many she pick every hour.

Let set up a fraction to make the equation equivalent

\frac{2 \frac{1}{3} }{ \frac{1}{4} }  =  \frac{x}{1}

1/4 goes into 1 4 times. so we would multiply 4 by 2 1/3 to find the x value.

2\frac{1}{3}  \times 4

2 \frac{1}{3}  \times  \frac{12}{3}

\frac{7}{3}  \times  \frac{12}{3}

\frac{84}{9}

9 \frac{3}{9}

9\frac{1}{3}

so the answer is D
