Given:
m∠BAC = 46° (angle a)
m∠CBA = 54° (angle b)

It is also given that AB is parallel with CD, so that means the points on AB is the same with the points on CD ( corresponding angles).

So ECD=BAC=45 and EDC=CBA=54

And the sum of the interior angle of a triangle is 180 degrees so we can work out that,

46+54+ angle DEC=180
angle DEC=180-46-54
angle DEC=80

If a number is ____, then the number is less than its absolute value. (Can you help me fill in the blank?in class we were learni

mylen [45]

It would be negative.

Absolute value is basically asking how far away something is from 0.

So say you had a number, 7. 7's distance from 0 is 7, so it would still be 7.

However, when absolute value really plays in is negative numbers. If you had -7, the distance from 0 would still be 7. It wouldn't be -7, so the absolute value of -7 would be 7.

And a negative version of a number is always less than the positive number.

Hope this helped!

HIIIIII 2 QUESTIONS IN THE 2 PICS HELP PLS

skelet666 [1.2K]

Answer:

(1)C- Trapezoid

(2)D-20 square feet

Step-by-step explanation:

Question 1

A cross-section of a rectangular pyramid cut perpendicular to the base but not passing through the top will have two parallel sides where one of the sides will be longer. Therefore, the shape which describes the cross-section will be a trapezoid.

Question 2

The base of the Triangle = 5 feet

Height of the Triangle = 8 feet

$\text{Area of a triangle}=\dfrac12 \times $Base \times Height\\=\dfrac12 \times 5 \times 8\\=20 ft^2$
