Answer:

A = 1.89 cm^2

Step-by-step explanation:

The base = 2.1

The height = 1.8

The formula for area of a triangle is given by

A = 1/2 b*h

A = 1/2 (2.1) * 1.8

A = 1.89 cm^2

Find the area. The figure is not drawn to scale

poizon [28]

Answer:

96 square inches.

Step-by-step explanation:

From given picture we see that

BC=8 in

AD=10 in

Given that

AD=AB

Then AB=10 in

Apply Pythagorean theorem in triangle ABC to find AC

$(hypotenuse)^2=(base)^2+(perpendicular)^2$

$(AB)^2=(BC)^2+(AC)^2$

$(10)^2=(8)^2+(AC)^2$

$100=64+(AC)^2$

$100-64=(AC)^2$

$36=(AC)^2$

take square root

$6=AC$

Then area of triangle ABC $=\frac{1}{2}\left(base\right)\left(altitude\right)$

$=\frac{1}{2}\left(8\right)\left(6\right)=24$

There are total 4 congruent triangles.

Then total area of the given figure = 4(24)=96 square inches.

Given that f(x) = 2x −5, find the value of x that makes f(x) = 15.

svp [43]

F(x) = 2 x - 5

15 = 2 x - 5

2 x - 5 = 15

2 x = 15 + 5

2 x = 20

x = 20 / 2

x = 10

hope this helps!
