[Right Triangles Only] SOHCAHTOA
[Right Triangles Only] cosθ = adjacent over hypotenuse

Step-by-step explanation:

Step 1: Identify Variables

Angle θ = 30°

Adjacent Leg = x

Hypotenuse = 8

Step 2: Solve for x

Substitute in variables [cosine]: $\displaystyle cos(30^\circ) = \frac{x}{8}$
[Multiplication Property of Equality] Isolate x: $\displaystyle 8cos(30^\circ) = x$
Rewrite: $\displaystyle x = 8cos(30^\circ)$
Evaluate: $\displaystyle x = 4\sqrt{3}$

Someone please help me

olganol [36]

Step-by-step explanation:

A and B are the legs of the triangles.

C is the hypotenuse.

12^2 + x^2 = 20^2

144 + x^2 = 400

-144 -144

x^2 = 256

x = 16

The length of the second leg is 16.

Find the minimum and maximum possible areas for a rectangle measuring 4.15 cm by 7.34 cm. Round to the nearest hundredth. A. min

Shalnov [3]

This is probably in the context of a discussion of significant figures and accuracy.

When we record a measurement of 4.15 cm with two significant figures, that means we believe the exact value is in the range from 4.145 cm to 41.155 cm

Similarly 7.34 really means between 7.335 and 7.345 cm.

The minimum area rectangle is

$4.145 \times 7.335 = 30.403575 \approx 30.40$

The maximum area rectangle is

$4.155 \times 7.345 =30.518475 \approx 30.52$
