Answer:
it's a scalene triangle whose all sides are different
Answer:
3x +89 + 8x + 58 =180 (they are supplementary angles, so added together they are equal to 180)
11x + 147= 180 (combine like terms on the left side of the = sign)
11x= 33 (subtract 147 from both sides and then divide by 11 to isolate x)
x= 3 (this is x)
3x +89 (this is the measure of angle MON, plug in x and solve)
3(3)+89
9+89
98 degrees (this is your answer)
Step-by-step explanation:
By Cramer's rule, the solution can be found as the ratio of determinants. The numerator is the matrix with the right-side constants replacing the coefficients of the variable of interest. The denominator is the matrix of coefficients.
The solution is ...
... B. (1, 4)
Answer:
2764.8cm³
Step-by-step explanation:
Looking at the diagram, the barn is a combination of 2 geometric shapes, a cuboid and Triangular prism
Step 1
Find the volume of the cuboid
Volume of the cuboid = Length × Width × Height
Length = 10cm
Width = 20.4cm
Height = 11.2cm
Volume = 10cm × 20.4cm × 11.2cm
Volume = 2284.8cm³
Step 2
Volume of Triangular prism = 1/2 × base × height × length
= 1/2 × 8 × 12 × 10
= 480cm³
Total volume = 2284.8cm³ + 480cm³
= 2764.8cm³
16 because you divide i hour by 15 and multiply that by 4:)
