Answer: True
Step-by-step explanation: A rectangle is a parallelogram with all its interior angles being 90 degrees. A rhombus is a parallelogram with all its sides equal. This means that for a rectangle to be a rhombus, its sides must be equal.
Yw and mark me as brainiest pls
Answer:
The largest angle needed is 
.
Step-by-step explanation:
To determine the larges angle as required, let us apply the cosine rule.
= 
+ 
- 2ab Cos C
Since in triangles, the longest side is opposite to the largest angle, then;
= 
+ 
- 2(8 x 12) Cos θ
225 = 64 + 144 - 192 Cos θ
225 = 208 - 192 Cos θ
192 Cos θ = 208 -225
192 Cos θ = -17
Cos θ = 
Cos θ = -0.08854
θ = 
-0.08854
= 95.07962
θ =
The largest angle needed is .
Answer:
The answer is 36 meters long.
Step-by-step explanation:
You start with the difference between 120 and 30 meters. 30 is 1/4 of 120, so all you do is do the opposite with 9. What's 4/1 times more than 9 and you get your answer.
Answer:
x=40
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+102+38 = 180
Combine like terms
x + 140 = 180
Subtract 140 from each side
x+140-140 = 180-140
x = 40
The percentage would be 4% because you have to subtract 20 from 16 to find the percentage and that would be 4. :D
Hope this helped. :D<span />
