How do I work this out???
Finger [1]
Okay so form a right angle triangle and the angle of that is 65 as it is right angle so 90 - 25= 65. label the sides like the pic below. 

we have the hypothenuse as well as the angle and we are trying to find the o(opposite side) 

o/h =sin
sin 65=23/h
sin 65 = 23/x
23/sin 65=x 
x=25.4

Which equation is the inverse of 2(x - 2)^3=8(7+y)​
irina1246 [14]

Answer:

\large\boxed{y=2\pm\sqrt{28+4x}}

Step-by-step explanation:

2(x-2)^2=8(7+y)\\\\\text{exchange x to y, and vice versa:}\\\\2(y-2)^2=8(7+x)\\\\\text{solve for y:}\\\\2(y-2)^2=(8)(7)+(8)(x)\\\\2(y-2)^2=56+8x\qquad\text{divide both sides by 2}\\\\(y-2)^2=28+4x\iff y-2=\pm\sqrt{28+4x}\qquad\text{add 2 to both sides}\\\\y=2\pm\sqrt{28+4x}

The ratio of three angle are 3:4:5 <br>what is the highest angle of the triangle??
SCORPION-xisa [38]
The sum of the sides of a triangle is equal to 180º.
The three angles will be: 3x,4x and 5x. 
we can suggest the following equation:
3x+4x+5x=180

12x=180
x=180/12
x=15

The angles would be:
3x=3(15)=45
4x=4(15)=60
5x=5(15)=75

Answer: the highest angle would measure 75º.
