Answer:
The smaller angle is 35 and the larger one is 145.
Step-by-step explanation:
In order to find this, we need to express the larger angle in terms of the smaller angle (x).
4x + 5 = large angle.
Now that we have this, we can add them together and set equal to 180.
x + (4x + 5) = 180
5x + 5 = 180
5x = 175
x = 35
Now that we have the value of the smaller angle, we can plug in to get the larger angle.
y = 4x + 5
y = 4(35) + 5
y = 140 + 5
y = 145
Answer:
x = 9
Step-by-step explanation:
first, you would subtract 1 from 80 and get -9x = -81 then you can just divide -81 by -9 or 9 from 81, either way, you'll have x = 9
square root of negative is an imaginary solution or number. meaning it exist somewhere. square root of 64 is 8 and the square root of 25 is 5. "i" represent imaginary number
Answer:
B
Step-by-step explanation:
Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.
8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.
Step-by-step explanation:
A is 20+90+A=180. A=70 (corner)
So the sine of 20 is 0,3420
So we have
Sine of 20 =CA÷7 => CA is 2.3 so you should write 3
