2x + 14 = 90
2x + 14 - 14 = 90 - 14
2x = 76
x = 38

What is the measure of Angle 1

Romashka [77]

M<1 = 125 degrees. This is because angle 1 next to it say it is angle 3 is 55 degrees. Angle 3 and 1 are supplementary (meaning they add up to 180 degreees). SO you do 180-55 which is equal to 125 degrees.

The map of a biking trail is drawn on a coordinate grid. The trail starts at P(−2, 2) and goes to Q(5, 2). It goes from Q to R(5

love history [14]

Answer:

The total length (in units) of the biking trail is 17 units.

Step-by-step explanation:

o find distance between points A(x¹, y¹) and B(x², y²), we use formula:

$d = \sqrt{(x^{2}-x^{1})^{2}+(y^{2}-y^{1})^{2}}$

The trail starts at P(−2, 2) and goes to Q(5, 2).

So, the distance PQ will be calculated as:

$PQ = \sqrt{(5^{}-(-2)^{})^{2}+(2^{}-2^{})^{2}$

$PQ = \sqrt{(49^{}+0)$

PQ = 7 units

Then the trail goes from Q(5, 2) to R(5, −5).

So, the distance QR will be calculated as:

$QR = \sqrt{(x^{2}-x^{1})^{2}+(y^{2}-y^{1})^{2}}$

$QR = \sqrt{(5^{}-5^{})^{2}+(-5^{}-2^{})^{2}$

QR = 7 units

And then from R(5, −5) to S(8, −5).

$RS = \sqrt{(8^{}-5^{})^{2}+(-5^{}-(-5)^{})^{2}}$

QR = 3 units

Hence, the total length of the biking trail is:

PQ + QR + QR = 7 + 7 + 3 = 17 units

A cone has a volume of 2,355 cubic inches and a height of 10 inches. How many inches is the diameter of the cone

Neporo4naja [7]

Hello there,

Okay well first we right down what we already know:

- volume of 2,355 cubic inches

- the height is 10 inches

Now we write down the equation for the volume of a cone: V = πr² $\frac{h}{3}$

lets plug in what we know into the equation

2,355 = πr² $\frac{10}{3}$

now we simplify to solve for r

2,355 / 10/3 = 706.5 = πr²

706.5/π = r²= 224.89

now since its r² we take the square root of 224.89

r = 15 inches

for diameter we multiply 15 by 2

diameter = 30 inches

Hope I helped,

Amna
