A right triangle has a base that measure 39 inches and a height that measures 80 inches. What is the length of its hypotenuse?

guajiro [1.7K]

The Pythagorean Theorum formula is a(squared) + b(squared)= c(squared). If you plug in the numbers, the equation is 39(squared) + 80(squared)= c(squared). That simplifies to 1521+6400=c(squared). Adding results in 7921=c(squared). Finally, when you take the square root of both sides, you are left with 89=c (aka the hypotenuse)

inn [45]

Your question is incomplete.

Answer choices not apply.

But if this is your question in the picture below then this is your answer..

Answer:

The line intersects the y-axis at (0, −2).

The equation of the line is y = −x − 2.

The line intersects the x-axis at (−2, 0).

Answer: A; 6.3%

Step-by-step explanation:

Problem 1

For the first problem, we first want to find y so that we can plug it into the expression.

We can use elimination method for the system of equations to solve.

3x+3y=21

3x-y=5

We subtract both equations to eliminate x.

4y=16 [divide both sides by 4]

y=4

Now that we know y, we can plug it into the expression.

$\frac{4}{2} -3$ [divide]

$2-3$ [subtract]

$-1$

We know that the answer is A.

Problem 2

For the second problem, we need to know how to calculate percent error. The formula for precent error is $\frac{|measured-exact|}{exact} *100%$ . We know that the exact value is 80 because the buyer was supposed to given 80. 75 is the measured value because that was what the buyer was given.

$\frac{|75-80|}{80} *100%$ [subtract]

$\frac{|-5|}{80} *100%$ [solve absolue value]

$\frac{5}{80} *100%$ [divide]

$0.0625*100%$ [multiply]

$6.25$

Since the problem said to round to one decimal place, we know that the answer is 6.3%.

Evaluate 4|-2| - |-3|

Nitella [24]

As we know these two lines mean | | a modulus sign. The modulus symbol is sometimes used in conjunction with inequalities. A modulus sign in simple words just ignores the sign and gives us the absolute value.

For example in this case the modulus gives us 4 x 2 - 3. As you can see the modulus sign has ignored the original negative signs with the numbers.

So after evaluating the equation the answer comes out to be 8 - 3 which is equal to 5.

Work out the angles marked with letters. Give reasons for each answer.

german

A. angel a is 50 bc since it is isosceles, the two ungiven angles equal the same (180-80=100, 100/2=50)
B. 180=28+28+b, 180=56+b, 124=b
