Answer:
48 units^2
Step-by-step explanation:
So i split the arrow to make it just one rectangle and one triangle
Area of rectangle
= 4×10
= 40 units^2
Area of triangle
= (12-10)×8×1/2
= 2×4
= 8 units^2
Total area of the arrow
= 40+8
= 48 units^2
Two groups (larger group A and smaller group B) can use any variables instead of a and b.
A + B = 20 (because you have a total of twenty objects)
2A = 3B
In group A there is a total of 12 objects and in B there is a total of 8 objects
Answer:
1176 squared units
Step-by-step explanation:
You need to use the formula for finding area (Length x Width) to find the surface area of each face. For example, 7 times 21 is 147, so that face by itself is 147 squared units
1. 2+(6*(4)^2)
2+(6*(16))
3. 2+(96)
4. 98 is the answer to the question
Answer:
Step 3.
m∠ AEB = m∠ CED .........By Vertical Angles Theorem.
Step-by-step explanation:
Vertical Angles Theorem:
Vertical angle theorem states that vertical angles, angles that are opposite each other and formed by two intersecting lines,are congruent.
If two lines intersect each other we have two pair of vertical opposite angles. As shown in the figure.
Here,
∠ 1 and ∠ 2 are vertical opposite angles and also they are equal.
∠ 3 and ∠ 4 are also vertical opposite angles and also they are equal.
For,
step 3. m∠ AEB = m∠ CED
Therefore, the reason for step 3 of this proof is Vertical Angles Theorem.
