Answer:
h = 55
Step-by-step explanation:
the sum of the 3 angles in a triangle = 180°
the 2 unknown interior angles = 180 - 2h ( straight angle ), hence
the sum of the 3 angles
180- 2h + 180 - 2h + 40 = 180
400 - 4h = 180 ( subtract 400 from both sides )
- 4h = - 220 ( divide both sides by - 4 )
h = 55
INCREASE IN %: [(40280-1591)/1591]X 100% = 2,432&
For your info the increase between 2 amounts A₁ & A₂ =(A₁-A₂)/A₁
Answer: the formula is r you have it right there
Step-by-step explanation:
I think that there would be 20 trucks because <span>6 + 10 + 14 + 15 = 45, </span><span>6 + 10 + 14 + 15 = 45, </span><span>45 + 45 = 90 </span>
<h3>
Answer:</h3>
6 cm, 8 cm, 12 cm
<h3>
Step-by-step explanation:</h3>
The perimeter of the reference triangle is ...
... (15 +20 +30) cm = 65 cm
Then the similar triangle has a scale factor of ...
... (26 cm)/(65 cm) = 2/5
Multiplying the side lengths of the reference triangle by 2/5, we get ...
... {15 cm, 20 cm, 30 cm) × 2/5 = {6 cm, 8 cm, 12 cm}
These are the side lengths of the smaller similar triangle. (Check: their sum is 26 cm.)
