144 is obtuse because it is more than 90. 78 is acute because it is less than 90

78- acute
144- obtuse

This is because anything less than 90 degrees is acute. Think of it as they are cute because they are tiny xD

=90 is right angel

And anything above 90 and below 360 is obtuse because it's fat xD

What is the slope between (-4,4) and (-6,6)

nalin [4]

$\textsf{Let's calculate the slope of the line passing thought the points (-4, 4) and (-6, 6) } \\ \textsf{using the following formula: }\mathsf{m = \frac{\Delta y}{\Delta x}} \textsf{ where m is the slope of the line.}$ $\textsf{So:}$

$\mathsf{m = \dfrac{\Delta y}{\Delta x} = \dfrac{4 - 6}{-4 - (-6)} = \dfrac{-2}{2} = -1}$

$\textsf{Hence the slope is -1.}$

A^2+2ab+b^2. solve for a=10 and b=50

qaws [65]

A² + 2ab + b² ; Solve when a=10 & b=50

Simply plug in 10 for a and 50 for b in our given equation :)

(10)² + 2(10)(50) + (50)²

Simplify.

100 + 20(50) + 2500

Simplify.

(100 + 2500) + 1000

Simplify.

2600 + 1000

Simplify.

3600

Hope I helped! :)

The cross section of a water bin is shaped like a trapezoid. The bases a a trapezoid are 20 feet and 6 feet long. It has a area

nekit [7.7K]

Answer:

the height of the cross section is 3 feet

Step-by-step explanation:

The computation of the height of the cross section is shown below:

Area = 1 ÷ 2 × (a + b) × h

39 = 1 ÷ 2 × (20 + 6) × h

39 = 1 ÷2 × 26 × h

39 = 26 ÷ 2 × h

39 = 13 × h

h = 39 ÷ 13

= 3 feet

hence, the height of the cross section is 3 feet
