Answer:
<em>x = 32</em>
Step-by-step explanation:
This is an isosceles triangle since two sides have length 10. The angles opposite the congruent sides are congruent. There is an angle measuring 116 deg, and two angles measuring x. The sum of the measures of the angles of a triangle is 180.
x + x + 116 = 180
2x + 116 = 180
2x = 64
x = 32
Answer:
18.7 cm²
Step-by-step explanation:
To work out the area of a triangle you have to use the formula
Where "B" is the base and "H" is the height
Since these are decimals, I like to convert them into fractions which makes them easier to calculate with
The base is 4.25 cm which will turn into 
The height is 8.8 cm which will turn into 
Now we use the formula
→ Convert to improper fractions
→ Simplify
→ Convert into decimal
18.7
Answer:
y=8
Step-by-step explanation:
l3l=3
3+5=8 so y=8
15+18+16=49 This is your total number of balls.
You have 15/49 green balls. Plug this fraction into a calculator: 15÷49. You get 0.306 To make this a percentage, multiply it by 100. You get 30.6 which rounds up to 31%. The probability of taking out a green ball is 31%. You can find the probability of the other colors by repeating the process. Message me if you have more questions.
