Answer:
Area ≈ 22 in²
Step-by-step explanation:
<u><em>Finding ST (Base)</em></u>
=> Tan 70 =
Where Opposite = ST and adjacent = 6
=> 1.22 * 6 = ST
=> ST = 7.33 in
<u><em>Now, Finding the area:</em></u>
=> Area =
Where Base = 7.33, Height = 6
=> Area = 1/2 (7.33)(6)
=> Area = (7.33)(3)
=> Area ≈ 22 in²
684,000. This should give you the correct answer as the 4 is the thousands place. Good luck :D
Dear Mgreeneyesd3, the ratios of children to teacher are proportional. 6/24=1/4, so if we do cross products, then we get 24=24.
The correct answer is A. 50°
Why?
We can find the angle using the opposite angles theorem. When two are lines are crossed, there are four angles formed between them, and the opposites angles will be always equal.
Now, since the seesaw board is parallel to the ground, we can deduct (applying the opposite angles theorem) that both angles formed at the base of the triangle are equal to 65°.
Also, we must remember that the sum of the three interior angles of a triangle will be always equal to 180°, so:
We have that the angle is equal to 50°.
Have a nice day!
