Answer:
A
Step-by-step explanation:
A. is the only correct solution to this question because you can also see that if we take 8 and divide this by 32 we get 1/4, so we know it is true.
Answer:
x+y=10 which means that x=10-y
Replace 10-y in the other equation which gives you:
10-y-y=6
10-2y=6
-2y=-4
y=2
Replace 2 in any of the 2 equations same answer for both:
x+y=10
x+2=10
x=8
So,


=512-8
=504
Hope this helps!
Answer:
so its the second one (1.28 , -3.68)
Step-by-step explanation:
its (32/25 , -92/25)
which equals to (1.28,-3.68)
Answer:
See below ~
Step-by-step explanation:
<u>Given</u> : 3 angles of a Δ
- (x + 5)°
- (x + 10)°
- (x + 15)°
<u>Solving</u> :
- According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°
- x + 5 + x + 10 + x + 15 = 180
- 3x + 30 = 180
- x + 10 = 60
- x = 50
<u>Finding the angles</u>
- x + 5 = 50 + 5 = 55°
- x + 10 = 50 + 10 = 60°
- x + 15 = 50 + 15 = 65°
Answer:
x = 4
Step-by-step explanation:
This is special right triangles
For the triangle on the bottom, the shorter leg is x, the longer leg is x * √3, and the hypotenuse is x *2. This means that the shorter leg is 2 since you the longer leg is that side multiplied by √3. The hypotenuse is x *2, which is 2 * 2 which equals 4.
Now we have one side of the bigger triangle. This triangle is a 45-45-90 triangle, and the rule is that the two legs are x, and the hypotenuse is x *2. Since we found a leg and not the hypotenuse of the bigger triangle, and the two legs are congruent, that means x is 4.
