Answer:
D
Step-by-step explanation:
We name the corners of the triangle as the attached image.
As we can see, triangle ABC is a right-angled triangle with Angle B equal to 90 degree.
As ABC is a right triangle, so that total measures of angle A and angle C is 90 degree
=> m∠A + m∠C = 90
=> m∠A + 45 = 90
=> m∠A = 90 - 45 = 45
=> m∠A = m∠C
So that ABC is also an isosceles triangle.
=> AB = AC = x
As ABC is a right triangle, according to Pythagoras theorem, we have the following equation:
AB^2 + BC^2 = AC^2
=> x^2 + x^2 = 20^2
=> 2.x^2 = 400
=> x^2 = 400/2 = 200
=> x = ≈ 14.14
So that x ≈ 14.14, the correct answer is D
Collect like terms (x + 7x) + (-1 + 4 - 3)
Simplify
Answer: 8x
Step-by-step explanation:
Hey there!!
I hope you remember that mid-segment theorem, in which it is stated that, line which passes through the midpoint of one side triangle bisects base, are parallel to another side of triangle and that line is half of parallel side. (i.e CB = 1/2 of RT) .
Now, Let's simply solve it.
Put their values as given in question.
Simplify them.
2x + 38 = x +29
2x - x = 29 - 38
x = -9.

Answer:
<em>The remainder is -12. Choice d)</em>
Step-by-step explanation:
<u>The Remainder Theorem</u>
The polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by (x-r) is equal to f(r).
We have the polynomial
To evaluate the remainder when P is divided by a+2, we only have to find P(-2):
The remainder is -12. Choice d)
