Answer:

Step-by-step explanation: How do you find the 3rd angle of a triangle?

Image result for im not sure on how to do this If one angle of a triangle is 30° more than twice another angle, and the third angle is equal to the sum of the first two angles, find the measure of each angle.

The three angles of any triangle add up to 180 degrees. Since you know two angles (35 and 40), add them together, then subtract the total from 180 to determine the degree of the third angle.

Use the substitution method.

E=number of eagles
c=number of condors

ttoal is 480
c+e=480

5 times as many condors and 9 times as many eagles totals 3260
5c+9e=3260

we have
c+e=480
5c+9e=3260

eliminateion
elmiminate c
times first equation by -5

-5c-5e=-2400

add to other equation

-5c-5e=-2400
<u> 5c+9e=3260 +</u>
0c+4e=860

4e=860
divide both sides by 4
e=215

sub back

c+e=480
c+215=480
minus 215 from both sides
c=265

thiis spring is

265 condors
215 eagles

Answer:

5 and 4

Step-by-step explanation:

2(x-3)^2➡ 2×(x^2-6x+9) ➡ 2x^2-12x+18 = 6x-22

transfer and add like terms

2x^2-12x-6x=-22-18

2x^2-18x = -40

2x^2 - 18x + 40 = 0

(2x-8)(x-5)

x = 5 or, x = 8/2 ➡ 4
