Step-by-step explanation:
The centroid O cuts every median in the ratio 2:1. The distance between a vertex and the centroid is twice the distance between the centroid and the midpoint of the opposite side.
Therefore: |OD| = 2|OCI
3x-2=2(5x)
3x-2=10x

Let
h---------> building tall
we know that
tan 74°=h/34---------> h=34*tan 74°--------> 34*3.487------> 118.57
h=118.6 ft
the answer is h=118.6 ft
Answer:
B
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
sum the parts of the ratio 3 + 3 + 4 = 10 parts
divide 180° by 10 to find one part of the ratio
= 18° ← 1 part of the ratio
3 parts = 3 × 18° = 54°
4 parts = 4 × 18° = 72°
thus the 3 angles are 54°, 54° and 72°
All 3 angles are acute angles
Hence an acute angled triangle
It can grow at a rate of 6 inch a day .5*12=6.
Answer:
x= - 35 over 89
Step-by-step explanation:
Step 1: Simplify both sides of the equation.

x−23=18x−18
Step 2: Subtract 18x from both sides.

x−23=−18
Step 3: Add 23 to both sides.
