Answer:
remember,a percent means "per 100".You can describe the change as a fraction comparing the amount of change to the original and then use a proportion to rewrite your problem as a percentage out of 100.
The answer is 1.94, I used a calculator, just letting u know
Answer:
218,205,858,257,659,822,002
Step-by-step explanation:
The angles should add to 540, so
b+ (3/2)b+(b+45)+(2b-90)+90=540
First combine like terms
5.5b+45=540
Then subtract 45 from both sides
5.5b=495
Divide both sides by 5.5
b=90
Final answer: b=90
Answer:
Angle GBH:
Angle ECD: 34
Angle HGB: 20
Angle FGH:
Step-by-step explanation:
Find all of the angles, some are needed to find others. Use the given angles...
FEC is 124, so the other side of it, CED must be 180-124 which is 56
Now we know CED is 56 and CDE is 90, and a triangles angles add up to 180, therefore angle ECD is 180-56+90, which is 34
Now we can find HCE, 180-90+34, which is 56
Angle CBG is 70 because 180-110 is 70
You can find angle HGB by looking at angle BCG which is 90 and angle CBG which is 70 and subtracting them from 180. 180-90+70=20
