Answer:
I HOPE THIS WILL HELP YOU :)
Step-by-step explanation:
115°=17x-4
adding 4 on both sides
115°+4=17x-4+4
119°=17x
dividing 17 on both sides
119°/17=17x/17
x=7
now we find the measure of angle
17(7)-4
=119-4
=115° same as angle R
First, you have to calculate the height.
Pythagorean Theorem:
a^2+b^2=c^2
Slant height=c^2
Radius=b^2
So, a^2+6^2=16^2
a^2+36=256
a^2=220
a=14.832397
Surface Area = πr(r+ square root of h^2+r^2)
Surface Area is approximately 414.69
Answer: 1/2
Step-by-step explanation:
Number of red balloons = 17
Number of purple balloons = 11
Number of orange balloons = 3
Number of green balloons = 1
Number of yellow balloons = 2
Total number of balloons = 34
The probability that a randomly selected balloon will be red will be:
= Number of red balloons/Total number of balloons
= 17/34
= 1/2
