Answer:
<em>Angle ABD is 22°</em>
Step-by-step explanation:
<u>Angles in a Triangle</u>
The sum of the internal angles in a triangle is 180°.
Consider the triangle BCD.
The angle CBD is 53°.
The angle BCD is 49°
The missing angle of the triangle BDC is the quantity needed to complete 180°, that is:
angle BDC=180°-53°-49°=78°
Now consider the triangle ABD
The angle ADB is supplementary of BDC, thus:
angle ADB = 180° - 78° = 102°
Finally, the angle ABD is the quantity needed to complete 180°:
angle ABD = 180° - 102° - 56° = 22°
Angle ABD is 22°
Answer:
17 m² or 17 square meters
Step-by-step explanation:
A trapezoid has base lengths of 5 meters and 3.5 meters. If the height of the trapezoid is 4 meters, what is the area of the trapezoid?
Area of a trapezoid =1/2(b1 + b2)h
Where
b1 = First base length = 5m
b2 = Second base length = 3.5 m
Height = 4m
= 1/2(5m + 3.5m) × 4m
= 1/2(8.5m) × 4m
= 1/2 × 8.5m × 4m
= 17 m²
Therefore, the area of the trapezoid is 17 m² or 17 square meters
Here is the equation: (gas=g)
8.5g= 23.94
All you need to do is the inverse of multiplication on the other side. (division)
23.94/8.5= 2.81647.....
g= 2.82 (rounded to the hundredths place)
I hope this helps!
