Hi so imagine a tent... It looks like a pyramid right?
Well when its asking for a tent flap, its talking about one triangle of the pyramid.
So its asking you to find the area of one triangle of the pyramid.
Does this make sense??
So the formula for an area of a triangle is (b*h)/2
So the answer is multiply the two numbers together then divide by 2.
Does this make sense?
Answer:
8) 10°
9) X can not be determined.
10) 10°
11) 12 units.
Step-by-step explanation:
8) The three sides of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each angle will be 60°.
So, 6x = 60°
⇒ x = 10°.
9) The three angles of the given triangle are equal. Hence, the triangle is an equilateral triangle, hence each side will be equal.
So, 6x - 5 = 6x
So, x can not be determined from this equation.
10) Δ KLM is equilateral, so, KN will bisect ∠ MKL. So, ∠ NKL = 30°
Hence, 3x = 30°
⇒ x = 10°
11) In Δ XYZ, XZ = XY , so, ∠ Z = ∠ Y.
Again, ∠ X is given to be 60°.
Therefore, each angle is 60°.
So, the triangle XYZ is equilateral, and each side will be equal.
So, 3x + 8 = 4x - 4
⇒ x = 12 units. (Answer)
Answer:
Fraction: 21/40
Decimal: 0.525
Step-by-step explanation:
(-3/5) x (-7/8)
-0.6 x -0.875
= 21/40 OR 0.525

Answer:
C
Step-by-step explanation:
It is the graph of f(x) translated 3 units down. Think about in numerical terms,
if y = 5 y-1 = 5- 1 = 4, so that's what is happening with all numbers on the y axis. You have y = f(x) and you do y-3 = f(x)-3, so, all "y" points are translated 3 units down
