60°, 60°, 60°
90°, 90°, 90°

Answers

Answer:

The first one! 45,45,90

Step-by-step explanation:

The sum of angle is 180, so Only

45+45+90=180

50+50+90=190 it is greater than 180 ist not Ok

60+60+90=210 it is not ok

90+90+90=270 is not ok

Answer:

you wil definetly find 90

20×+4=4(5x+1) how many solution are in this equation

Answers

Simplify both sides of the equation

(20)(4)= 4(5x+1)

Simplify

80 = 20x+4

Flip the equation

20x+4 = 80

Subtract 4 from both sides

20x+4-4 = 80-4

20x = 76

Divide both sides by 20

20x/20 = 76/20

x= 3.8

There is one solution in this equation

Factor completely: 81x^4 – 1A. (9x + 1)(9x – 1)
B. (9x^2 + 1)(9x^2 – 1)
C. (3x^2 + 1)^3(3x – 1)
D. (9x^2 + 1)(3x + 1)(3x – 1)

Answers

Using this: a²-b²=(a+b)(a-b)

81x^4-1=

(9x²)²-1=

(9x²-1)(9x²+1)= (in the bold half we use the formula again)

(3x+1)(3x-1)(9x²+1)

So the answer is D

$81x^4-1=\n(9x^2)^2-1^2=\n(9x^2+1)(9x^2-1)=\n(9x^2+1)((3x)^2-1^2)=\n(9x^2+1)(3x+1)(3x-1)$
