Answer:
ummm
Step-by-step explanation:
do u have a picture to show?
Do the Pythagorean theory to find the unknown side by doing:
c^2 = a^2 - b^2
Then you’ll have two sides and two angles.
Do sine law.
Sin(angle) / side (opposite to it) = Sin(angle) / side (opposite to it)
Answer:
72 sq. inch.
Step-by-step explanation:
9 inches in feet is 9/12 = 0.75 feet.
We can set up a ratio to figure out the width of the scale drawing.
This means <u>"if 36 feet is 0.75 feet in drawing, how much (let that be x) is 32 feet?"</u>
<u />
let's cross multiply and solve for x:
<em>So width is 2/3 feet and length is 0.75 feet.</em>
<em>Converting back to inches (since we need the area in sq. inches):</em>
<em>2/3 feet = 2/3 * 12 = 8 inches, and</em>
<em>0.75 feet = 0.75 * 12 = 9 inches</em>
<em />
<em>Hence, area is 8 * 9 = 72 sq. inches.</em>
992,449 rounded to the nearest hundred thousands is 1,000,000.
C. 65 degrees.
Triangles must equal 180 degrees. The given 50 means the rest of the triangle is equal to 130. I believe because of the Side-Angle-Side theorem of triangles (if my knowledge of proofs from 3 years ago is still with me), the two remaining angles are equal to each other. Let's call them X. 2x = 130. Divide both sides by 2. 130/2 = 65. So x=65
