Answer:
<u><em>1: "An equilateral triangle is never an obtuse triangle" & "An equilateral triangle is never an isosceles triangle."
</em></u>
<u><em>
</em></u>
<u><em>2: Acute Isosceles Triangle
</em></u>
<u><em>
</em></u>
<u><em>3: False! Option B.
</em></u>
<u><em>
</em></u>
<u><em>4: D</em></u>
Step-by-step explanation:
2: Isosceles Triangles have two equal sides. An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.
3: An <u>equilateral triangle</u> is a triangle in which all the sides and all the angles are equal.
4: In order for a triangle to be <u>isosceles</u>, it has to have two same sides. For a triangle to be <u>equilateral</u>, all sides and angles need to be the same. Refer to reasoning in Question 2 for next explanation.

For #1 you have one leg of a right triangle measuring 4000 (the height of the mountain) and the other leg is 3000 (the distance that Mario is from Jenna). The angle of elevation is the one on the base of the triangle across from the right angle. To find the measure of the angle, use the tangent ratio: tan(A)=4000/3000, which could be simplified to tanA = 4/3. Do that on your calculator using the inverse tangent function to get that the angle of elevation from Mario to Jenna is 53 degrees.
For #2 you have another right triangle situation where the length of the hypotenuse is 20 and the base leg is 10. You are finding again the base angle across from the right angle. Use the cosA=10/20, aka cosA=.5. Again use the inverse cos function on your calculator to find the angle in question is 60 degrees.
Answer:
4th option
Step-by-step explanation:
Using the recursive rule and f(1) = - 4 , then
f(2) = f(1) + 5 = - 4 + 5 = 1
f(3) = f(2) + 5 = 1 + 5 = 6
f(4) = f(3) + 5 = 6 + 5 = 11
The first 4 terms are - 4, 1, 6, 11
