Answer : The value of x and y is, $90^o$ and $43^oC$

Step-by-step explanation :

First we have to calculate the angle B.

As we know that,

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Thus, $\angle B=\angle C$

Given : $\angle C=47^o$

$\angle B=\angle C=47^o$

$\angle B=47^o$

Now have to calculate the angle A.

As we know that the sum of interior angles of a triangle is equal to $180^o$ .

$\angle A+\angle B+\angle C=180^o$

$\angle A+47^o+47^o=180^o$

$\angle A+94^o=180^o$

$\angle A=180^o-94^o$

$\angle A=86^o$

Now we have to determine the angle y.

As we know that, line AD is an angle bisector. That means, it divides into two equal angles. So,

$\angle y=\frac{\angle A}{2}$

$\angle y=\frac{86^o}{2}$

$\angle y=43^o$

Now we have to determine the angle x.

As we know that the sum of interior angles of a triangle is equal to $180^o$ .

$\angle y+\angle B+\angle x=180^o$

$43^oc+47^o+\angle x=180^o$

$\angle x+90^o=180^o$

$\angle x=180^o-90^o$

$\angle x=90^o$

Thus, the value of x and y is, $90^o$ and $43^oC$

Someone please help!!

Answer:

y-6 = -7x + 21

Step-by-step explanation:

Find the slope

(-8 - 6)/(5-3)

-14/2 = -7

Now find the formula

y-6=-7(x - 3)

y-6 = -7x + 21

Another way to write it is

y= -7x + 27

Gabe drops a hammer from an apartment that is 30 meters above the ground. The height of the hammer in meters, h, after t seconds

anyanavicka [17]

Simplifying
h(t) = -1t2 + -2t + 30

Multiply h * t
ht = -1t2 + -2t + 30

Reorder the terms:
ht = 30 + -2t + -1t2

Solving
ht = 30 + -2t + -1t2

Solving for variable 'h'.

Move all terms containing h to the left, all other terms to the right.

Divide each side by 't'.
h = 30t-1 + -2 + -1t

Simplifying
h = 30t-1 + -2 + -1t

Reorder the terms:
h = -2 + 30t-1 + -1t

Kevin can travel 22 1/2 miles in 1/3 hour .What is the average speed in miles per hour?

Fantom [35]

You can choose to answer this with fractions or decimals. I'll choose fractions because we won't need calculators. 22 1/2 miles "in" 1/3 hour, means 22 1/2 mi divided by 1/3 hour.
22 1/2 = [(22×2) + 1] ÷ 2 = 45/2
So (45/2)mi ÷ (1/3)hr is the same as (45/2) × (3/1), or (45×3)/2 = 135/2, which is 67 1/2, or 67.5 mi/hr (mph).

MathUp Evaluating Expressions

AysviL [449]

Since the question is incomplete, answer will be subjective. An example of Evaluating Expressions is find h + 8 − 9 j − h; where h = 7 and j = 5.

<h3>What is the Evaluating Expressions?</h3>

The evaluating expressions is known to be a form of digital and printable board work that can help students in working on substituting values in terms of variables of an algebraic expression.

Evaluating the Expression below:

h + 8 − 9 j − h;

Therefore, where h = 7 and j = 5

7+ 8 − 9 (5) − 7.

SO: 7 + 8 - 45 -7

= -37

Therefore the answer to the Evaluating Expression is -37.
