(180(total angle measure of triangle)-50(EFG))/2(the other two angles have the same measure)=65


The angle CGE=180=CGF+EGF
180-65=CGF
115=CGF

we know that

An isosceles triangle has two equals sides and two equals angles

so

EF=GF

m∠EGF=m∠GEF

The sum of the internal angles of a triangle must be 180 degrees

m∠EGF+m∠GEF+m∠EFG=180\°

we have

m∠EFG=50\°

2m∠EGF+50\°=180\°

2m∠EGF=180\°-50\°

2m∠EGF=130\°

m∠EGF=65\°

therefore

<u>the answer Part a) is</u>

the measure of angle EGF is 65\°

Part b) What is the measure of m∠CGF?

we know that

m∠CGF+m∠EGF=180\° ---------> by supplementary angles

substitute values

m∠CGF+65\°=180\°

m∠CGF=180\°-65\°

m∠CGF=115\°

therefore

<u>the answer Part b) is</u>

the measure of angle CGF is 115\°

Several friends bought flowers to make table centerpieces. write the ratios of purple flowers to white flowers for each friend.
Zina [86]

The ratio for Rowan = <u>4:1</u>.

The ratio for Marcia = <u>10:1</u>.

The ratio for Jillian = <u>5:1</u>.

The ratio for Lulua = <u>6:1</u>.

The smallest ratio among these for purple to white flowers is for Rowan, that is, <u>4:1</u>.

Ratios are fractions in the simplest form representing the relationship between two quantities.

The ratio of purple to white flowers for each friend can be shown as:-

Rowan:

The number of purple flowers = 8

The number of white flowers = 2

Thus, the fraction of purple to white flowers = 8/2 = 4/1.

Thus, the ratio for Rowan = 4:1.

Marcia:

The number of purple flowers = 10

The number of white flowers = 1

Thus, the fraction of purple to white flowers = 10/1.

Thus, the ratio for Marcia = 10:1.

Jillian:

The number of purple flowers = 10

The number of white flowers = 2

Thus, the fraction of purple to white flowers = 10/2 = 5/1.

Thus, the ratio for Jillian = 5:1.

Lulua:

The number of purple flowers = 18

The number of white flowers = 3

Thus, the fraction of purple to white flowers = 18/3 = 6/1.

Thus, the ratio for Lulua = 6:1.

The smallest ratio among these for purple to white flowers is for Rowan, that is, <u>4:1</u>.
