Answer:
measure of angle A is 80 degree.
Step-by-step explanation:
isosceles triangle will have same base angles
first base angle is 50, and the second will also be 50
3 angles of a triangle will add up to be 180 degree.
A is the vertex angle.
So 50 + 50 + A = 180
100 + A = 180
A = 80.
Answer:
Latoya:
cran : lem = 2 1/5 : 1 4/5
= 11/5 : 9/5
= 11 : 9
Lem : total = 9 : 20
Parker:
cran : lem = 2 1/2 : 3 1/2
= 5/2 : 7/2
= 5 : 7
Lem : total = 7 : 12

You have to choose 1 sort of cheese from 3 ( 3 ways ). Also you have to choose 3 toppings from 12 different toppings:
12 * 11 * 10 = 1,320 ways.
In total: 3 * 1,320 = 3,960
Answer:
In 3,690 ways can pizza be made with 1 cheese and 3 toppings.
Suppose m∠1 = x degree
m∠2 = 17 x degree
As angle 1 & 2 are supplementary angles so
m∠1 +m∠2 =180 degree...... eq 1
Substituting the values of angle 1 & 2 in eq 1, we get
x +17x =180
18x=180
x= 180/18 =10 degree
17 x= 170 degree
m∠1 = 10 degree m∠2 = 170 degree.
