Answer:
(-∞ 2] ∪ [-4/3 ∞ )
Step-by-step explanation:
Given compound inequality,
( Subtraction property of inequality )
( Division property of inequality )
( a < b ⇒ - a > - b )
Hence, the solution of the given inequality is,
(-∞ -2] ∪ [-4/3 ∞ )
56° and 34°
complementary angles sum to 90° thus
3x - 10 + 2x - 10 = 90
5x - 20 = 90
add 20 to both sides of the equation
5x = 90 + 20 = 110
divide both sides by 5
x = = 22
angle 2x - 10 = (2 × 22) - 10 = 44 - 10 = 34° and
angle 3x - 10 = (3 × 22) - 10 = 66 - 10 = 56°
Answer:
Area of the base is 10.5 cm².
Step-by-step explanation:
Formula for the volume of the given oblique prism = Area of the triangular base × Vertical height between two triangular bases
Vertical height = 6 cm
Volume = 63 cm³
From the formula,
63 = Area of the triangular base × 6
Area of the base =
= 10.5 cm²
Therefore, area of the base is 10.5 cm².
