Find the area, in square feet, of a triangle whose base is 42⁄3 feet and whose altitude is 84⁄7 feet. A. 135⁄21 B. 20 C. 40 D. 2

CaHeK987 [17]

Answer:

Option B. $20\ ft^{2}$

Step-by-step explanation:

we know that

The area of a triangle is equal to

$A=\frac{1}{2}bh$

we have

$b=4\frac{2}{3}\ ft$

$h=8\frac{4}{7}\ ft$

Convert mixed numbers to an improper fractions

$b=4\frac{2}{3}\ ft=\frac{4*3+2}{3}=\frac{14}{3}\ ft$

$h=8\frac{4}{7}\ ft=\frac{8*7+4}{7}=\frac{60}{7}\ ft$

substitute the values

$A=\frac{1}{2}(\frac{14}{3})(\frac{60}{7})\\ \\A=\frac{14*60}{2*3*7}\\ \\A=\frac{840}{42} \\ \\A=20\ ft^{2}$

A student inscribes a triangle within a semicircle. What is the measure of ∠XYZ?

nata0808 [166]

Answer: a. 90°

Step-by-step explanation:

We know that the in a circle, the measure of an inscribed angle is half the measure of the central angle with the same intercepted arc.

In the problem∠XYZ is the inscribed angle

∠XYZ= $\frac{1}{2}\ arc(XZ)$

⇒ ∠XYZ= $\frac{1}{2}\angle{XZ}$

Since XZ is a diameter of the circle which is a line segment, thus ∠XZ=180°

∴ ∠XYZ= $\frac{1}{2}180^{\circ}=90^{\circ}$

∴ ∠XYZ= $90^{\circ}$

Therefore, a. 90° is the measure of ∠XYZ.
