CAN SOMEONE PLEASE HELP ME WITH THIS PLEASE!!

Hey there! :)

x = 31°.

Step-by-step explanation:

In this situation, we are given the measures of ∠B and ∠C. We need to solve for ∠A, since ∠A and ∠D are congruent.

Recall that all angles in a triangle sum up to 180°:

180° = 57° + 61° + m∠A

180° = 118° + m∠A

m∠A = 62°.

m∠A ≅ m∠D, so 62° = 2x. Solve for x:

62° = 2x

Divide both sides by 2:

62°/2 = 2x/2

x = 31°.

x=31

Step-by-step explanation:

the two triangle are equal and congruent so : ∠B=∠E=61

the sum of angles of a triangle=180

∠D+∠C+∠E=180

2x+57+61=180

2x=180-(61+57)

2x=180-118

2x=62

x=62/2=31

measure of ∠D is 62

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
