Answer:

105 cm²

Step-by-step explanation:

The figure is composed of a rectangle and a triangle

area of rectangle = 15 × 6 = 90 cm²

area of triangle = \frac{1}{2} bh ( b is the base and h the height )

Here b = 15 - 9 = 6 and h = 11 - 6 = 5 , thus

area of triangle = \frac{1}{2} × 6 × 5 = 3 × 5 = 15 cm²

Total area = 90 + 15 = 105 cm²

Snezhnost [94]
Area of a rectangle is length by width, width is x, length is x+8
x×(x+8)=240
x²+8x=240
x²+8x-240=0
Use the quadratic formula to solve
x=\frac{-b±\sqrt{b^{2}-4ac}}{2a}&#10;x=\frac{-8±\sqrt{8^{2}-4(1)(-240)}}{2(1)}&#10;x=\frac{-8±\sqrt{64-4(-240)}}{2}x=\frac{-8±\sqrt{1024}}{2}&#10;x=\frac{-8±32}{2}&#10;x=\frac{24}{2} OR \frac{-40}{2}&#10;x=12 OR -20
It is a distance so can't be negative, so the answer must be 12

Someone, please help me with this question.
Viefleur [7K]

Answer:

C.  95°

Step-by-step explanation:

Sumplementary angles sum 180°

144° + a = 180°

a = 180° - 144°

a = 36°

121° + b = 180°

b = 180° - 121°

b = 59°

The sum of internal angles of a triangle is 180°

a + b + c = 180°

36° + 59° + c° = 180°

c° = 180° - (36°+59°)

c° = 180° - 95°

c° = 85°

then:

c + n = 180°

85° + n = 180°

n = 180° - 85°

n = 95°
