Lines AE and GH are parallel indeed image below. The image will be used to prove that the sum of the measures of the interior angles ∆CGH is 180.

Which statement would be included in a proof of why C+G+H=180 ?

1. Angles F and H are congruent.
2. Angles C and E are congruent.
3. Angles A and G are congruent.
4. Angles F and C are congruent.

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
