Answer:
<em>102°</em>
Step-by-step explanation:
(3x - 12)° + (2x + 2)° = 180°
5x - 10 = 180 ⇒ x = 38
m∠A = (3x - 12)°
<em>m∠A</em> = (3×38 - 12)° = <em>102°</em>
Answer:
41
Step-by-step explanation:
We can obtain the area of a triangle where two sides and an included angle is given by saying; 1/2 ab sinθ
where a and b are the given sides of the triangle and θ is the included angle.
From the formula for the area of the triangle;
Area of a triangle = 1/2 ac sin B
Area of the triangle = 1/2 * 9 * 11 * sin 124
Area of the triangle = 49.5 * sin 124
Area of the triangle = 41
Your answer to this question is definitely C!
Answer: Trinomials often (but not always!) have the form x2 + bx + c. ... So, how do you get from 6x2 + 2x – 20 to (2x + 4)(3x −5)? Let's take a look. Factoring Trinomials
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Drop an altitude. Either of the two resulting right triangles with legs of length 5 and x and a hypotenuse of 10.
By the Pythagorean theorem, it follows that the answer is B.
