Answer:
1. H = 29 cm
2. θ = 44°
Step-by-step explanation:
1. We can find the height of the triangle by considering the isosceles triangle as two right triangles. The height can be found by using Pitagoras:
Where:
L: is the sides of the isosceles triangle = 42 cm
B: is the base = 30 cm
H: is the height =?
Then, the height is:
2. The two equal angles (θ) can be found using the following trigonometric identity:
Hence, the two equal angles are 44°.
I hope it helps you!
Step-by-step explanation:
Expression are problems with operations and terms, but no equal sign(s).
<u>Note: If a problem has an equal sign, it's an equation.</u>
*By eliminating the problems with equal signs, 12/4 =3 and 12 = 4 x 3 are incorrect.
12 + 4 - 3 and 12 - 4(3) are expressions, due to both problems not having an equal sign.
Answer:
Yes, John is correct.
