ale4655 [162]

Answer:

#5

Area = Area of bigger triangle - Area of small triangle

{ \rm{area = ( \frac{1}{2}  \times b_{b}  \times h_{b}) - ( \frac{1}{2} \times b_{s} \times h _{s} )}} \\  \\ { \tt{area = ( \frac{1}{2} \times 18 \times 7) - ( \frac{1}{2} \times (18 - 13) \times 7)  }} \\  \\ { \tt{area = (9 \times 7) - (2.5 \times 7)}} \\  \\ { \underline{ \tt{ \:  \: area = 45.5 \:  \: sq \: units \:  \: }}}

#8

Area = area of square + area of two right angled triangles

{ \tt{area = (s \times s) + 2( \frac{1}{2}  \times b \times h)}} \\  \\ { \tt{area = (6 \times 10) + (3 \times 5)}} \\  \\ { \underline{ \tt{ \:  \: area = 75 \:  \:  {m}^{2}  \:  \: }}}

I WILL GIVE BRAINLIEST
masha68 [24]

Answer:

Part A = 64 feet

Part B = 79 feet

Step-by-step explanation:

Part A

10 × 2 = 20 = Diameter

Formula is C = π × diameter

20 × π = 62.8318530718 feet = 64 feet

Part B

25 × 2 = 50

Same formula

50 × π = 157.079632679 feet

157.079632679 ÷ 2 = 78.5398163395 feet = 79 feet

divide by 2 because it is a semi circle

Hope his helped :)

WILL MARK BRAINLIEST
lutik1710 [3]

Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x - 10 + 6x + 5 + 4x - 10 = 180, simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15
