Answer: true
Step-by-step explanation:
Hello!
Let's think of this large triangle as a whole. If we add up the angles, we have 115°. The adjacent side to this angle is 9 feet. Let's try finding the opposite side. The tangent deals with these two.
tan115≈2.14
Therefore, x/9=2.14
We multiply both sides by 9 to find x.
x=19.26
Now let's find the length BC and subtract it from 19.26 to find our length. As we will deal with opposite and adjacent sides, we will find the tangent.
tan45=1
This means x/9=1
Therefore, BC=9
Now we can subtract from 19.26
19.26-9=10.26
Therefore, this length is 10.26 feet
I hope this helps!
14+30=44 (from his head to his waist)
76-44=32(he is 76 inch tall so substract 44 from 76 to find the length of feet-waist)
answer is 32
3 x 4x is 12x and three times negative one is negative three. Add these together to get 12x - 3. This is expanding singular brackets
Answer:
80 m²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A =
h (a + b)
where h is the perpendicular height between bases and a, b are the bases
Here h = 8, a = 14 and b = 6, thus
A =
× 8 × (14 + 6) = 4 × 20 = 80 m²
