Answer:
no
Step-by-step explanation:
using the converse of Pythagoras' identity
If the square on the longest side is equal to the sum of the squares of the other 2 sides, then the triangle is right.
longest side = 50 ⇒ 50² = 2500
16² + 14² = 256 + 196 = 452
since 452 ≠ 2500 then the triangle is not right
The scale factor is 4 (10/2.5).
Each side has increased by a factor of 4. Think of it logically, if the original rectangle had sides of 1,1,1/4,1/4, the perimeter would add to 2.5. In order to get the sides to add up to 10, each of the sides would need to be multiplied by 4. Then our sides would measure 4,4,1,1 with a perimeter of 10.
Answer:
x = 17/4 = 4.25
Step-by-step explanation:
We assume your multiplication symbol (×) is intended to be a variable (x).
Simplifying, we have ...
17 -10x +45 = 6x -10 +4
68 = 16x
68/16 = x = 17/4 = 4.25

<em>Check</em>
17 -5(2(4.25) -9) = -(-6(4.25) +10) +4
17 -5(8.50 -9) = -(-25.5 +10) +4
17 -5(-0.5) = 15.5 +4
17 +2.5 = 19.5 . . . . . . true
Answer:
f. for the x values I think its -1 & 5
Answer:
C. 65º
Step-by-step explanation:
180º- (62+53)=65º
a=65º
180º-(65+62)=53º
b=53º
180º-(53+62)=65º
c=65º
