Acute angles are angles less than 90°
100° is obtuse angle
70° is acute angle
Therefore the angle is 70°

Check all that are equivalent A=1/2h(b1+b2), 2A=hb1+b2, b1=2A/h-b2, b1=2(A-1/2hb2)/h

VMariaS [17]

Answer:

(A) $A=\dfrac12h(b_1+b_2)$

(D) $b_1=\dfrac{2(A-\dfrac12 hb_2)}{h}$

Step-by-step explanation:

Given that:

$A=\dfrac12h(b_1+b_2)$

$2A=h(b_1+b_2)\\2A=hb_1+hb_2\\hb_1=2A-hb_2\\b_1=\dfrac{2A-hb_2}{h} \\b_1=\dfrac{2(A-\dfrac12 hb_2)}{h}$

Therefore, A and D are equivalent

Answer:

<h2>Diameter = 10</h2>

Step-by-step explanation:

If the side of a triangle inscribed in a circle is a diameter, then it is a right triangle.

Use the Pythagorean theorem:

d - diameter

$d^2=8^2+6^2\\\\d^2=64+36\\\\d^2=100\to d=\sqrt{100}\\\\d=10$

Find X using the image.

Temka [501]

Answer:

x = 2

Step-by-step explanation:

The square of the tangent is equal to the product of the secant lengths to the near and far circle intersections.

(x +4)² = (2x -1)(2x -1 +9)

0 = (2x -1)(2x +8) -(x +4)² = (4x² +14x -8) -(x² +8x +16)

0 = 3x² +6x -24 = 3(x² +2x -8) = 3(x +4)(x -2)

This has solutions x = -4 and x = 2. Only the latter works in this geometry.

x = 2

Elodia [21]

Answer:

m=-2

Step-by-step explanation:

m=y2-y1/x2-x1

m=-2-8/3-(-2)

m=-2-8/3+2

m=-10/5

m=-2
