Answer:Yes, I checked.. it is option 2
Step-by-step explanation:
<h2>Question 9:</h2>
1. Use Pythagorean Theorem (a²+b²=c²) to solve for missing side of triangle and rectangle. x²+16²=20², or x²+256=400. So, x²=144, and x=12
2. Use formula: 1/2(h)(b1+b2). 1/2 (12) (30+14).
3. Simplify: 1/2 (12) (44)=1/2(528)=264
Area of whole figure is 264 square mm.
<h2>Question 10:</h2>
Literally same thing but with trigonometry.
1. Use sine to find out length of dotted line: sin(60°)=x/12
2: Simplify: 12*sin(60°)=x. x≈10.4 (rounded to the nearest tenth)
3. Use Pythagorean Theorem to find out last leg of triangle: 10.4²+x²=12²
4: Simplify: 108.16 +x²=144. x²=35.84 ≈ 6
5: Use formula: 1/2(h)(b1+b2). 1/2 (10.4) (30+36)
6: Simplify: 1/2 (10.4) (66) =343.2
7: Area of figure is about 343.2
Remember, this is an approximate answer with rounding, so it might not be what your teacher wants. The best thing to do is do it yourself again.
Answer:
This is a protractor question if you dont have one then try these on a calculator.
when angle is between two lines we need see where the hypotenuse is in the diagram and where is the adjacent.
And whether the triangle is right angle or not.
Try these
shift sin -1 x sin 9/6 (for opp/hyp)
shift sin -1 (9/6) (for opp/hyp)
shift sin -1 x sin 6/9 (for opp/hyp)
shift sin -1 (6/9) (for opp/hyp)
shift cos -1 x cos 9/6 (for adj/hyp)
shift cos -1 (9/6) (for adj/hyp)
shift cos -1 x cos (6/9) (for adj/hyp)
shift cos -1 (6/9) (for adj/hyp)
shift tan -1 x tan (9/6) ( for opp/adj)
and so on....
Step-by-step explanation:
14080 ft is the answer
