Answer:
A = 156 in ^2
Step-by-step explanation:
A of a rectangle is given by
A = l*w
A = 12*13
A = 156 in ^2
Answer:
35 ft²
Step-by-step explanation:
The shape is a triangle and its area is given by the formula below:
Area of triangle= ½ ×base ×height
Do note that the height has to be the perpendicular height, which is 5 ft in this case.
Area of triangle
= ½(14)(5)
= 35 ft²
Decompose the terms in the sum as

so there are 20 terms in the sum. Then our sum simplifies to

Now, if

we can reverse the order of terms to get the same sum,

so that doubling up the sum gives

So, our sum evaluates to

Answer:
uhm i can't see the bottom of the graph but if u look where it says 200 on the cash side u go up halfway to 240 making it meet the limit of 220? so then u go all the way left until u hit the orange line and when u hit it u go straight down giving u the answer
Step-by-step explanation:
Student is wrong An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.
<h3>What is exterior angle?</h3>
The Exterior Angle is the angle between any side of a shape, and a line extended from the next side.
The student make an error he states that the exterior angle of a triangle can never be a right angle.
The correct answer will be option D that is An exterior angle of a triangle can be adjacent to the right angle of a right triangle, so an exterior angle can be a right angle.I have also attached the diagram of the triangle for better understanding.
