Answer:
Missing angle = 135°
Step-by-step explanation:
Given:
Pentagon shape
Number of right angle = 3
Remain two angles are equal
Computation:
Sum of Pentagon angles = 540°
So,
90 + 90 + 90 + a +a = 540
270 + 2a = 540
a = 135°
Missing angle = 135°
No it’s wrong count down 3 and over 2 ur points should land on a corner
6W (-12x) + 7W (-8x) = 13W - 20x
Explanation:
6W + 7W = 13W
-12x - 8x = -20x
Answer: There are 126 red key chains.
Step-by-step explanation:
1. You know that 10% are yellow, then:
350*0.1=35 (35 key chains are yellow).
2. And you know that of the remaining key chains 3/5 there are green.
The remaining is:
350-35=315
Then:
325*3/5=189 (189 key chains are green).
3. Then, the number of key chains that are red is:
350-35-189=126 (126 key chains are red).
