Answer is 70degree because if angle 1 is 70 then angle 2 also will be the same then it means even angle 3 will be 70.

Can someone help me with this problem

user100 [1]

Answer:

About 110.6

Step-by-step explanation:

The sine of an angle is the length of the opposite side divided by the length of the hypotenuse.

$\sin 19= \dfrac{36}{x} \\\\x=\dfrac{36}{\sin 19}\approx 110.6$

Hope this helps!

This is really improtant

Oduvanchick [21]

To determine the lines that are parallel, you will need to find the missing angle length in the pairs of supplementary angles (totaling 180 degree).

180 - 114 = 66 degrees
180 - 112 = 68 degrees

Using these you can see the lines that are parallel. They have matching angle measurements.

c // f
d // e

Solve the simultaneous equation 4x-y=9 2x-3y= -23

MrMuchimi

Answer:

x = 5

y = 11

Step-by-step explanation:

y = 4x - 9

2x -3(4x - 9) = -23

2x - 12x + 27 = -23

-10x = -23 -27

-10x = -50

minus cancels out

x = 5

y = 4(5) -9

y = 20 - 9

y = 11

Question 20 fast please

kipiarov [429]

Answer:

Square root of 4 is 2

so 1+ $\frac{[1+\sqrt{2x-1]}^2 }{4}$ =4

frac{[1+sqrt{2x-1]}^2 }{4}=3

so 1+sqrt{2x-1]}^2=12

so 1+sqrt{2x-1}=V12

sqrt{2x-1}=V12-1

2x-1=(V12-1)^2=12-2V12+1=13-2V12

2x=13+1-2V12

2x=14-2V12

x=7-V12

x=7-2V3
