Answers

Answer 1

Answer:

Option (2)

Step-by-step explanation:

By applying tangent rule in the given right triangle,

tan(42°) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

tan(42°) = [tex]\frac{6}{\text{Width}}[/tex]

Width = [tex]\frac{6}{\text{tan}(42)}[/tex]

Width = 6.67

Therefore, width of the given triangle is 6.67 units.

Option (2) is the correct option.

5x + 7y = 3
2x + 3y = 1
Solve

Answers

Answer: x=2 and y=−1

Step-by-step explanation:

5x+7y=3for x:

5x+7y=3

5x+7y+−7y=3+−7y(Add -7y to both sides)

5x=−7y+3

x= −7/ 5 y+ 3 /5

Substitute −7 /5 y+ 3 /5  for x in2x+3y=1:

2( −7/ 5 y+ 3 /5 )+3y=1

1 /5 y+ 6 /5 =1(Simplify both sides of the equation)

1 /5 y= −1 /5

y=1

Substitute −1 for y in x

−7 /5 y+ 3 /5 : x=

x=2

x=2(Simplify both sides of the equation)

find for x

Answers

Answer:

120°

Step-by-step explanation:

The angle next to the x will be 40° due to the alternate angles so

x + 40° + 20° = 180° { being linear pair }

x + 60° = 180°

x = 180° - 60°

x = 120 °

Hope it will help :)

Answer:

120˚

Step-by-step explanation:

Since the two lines are parallel, they are alternate angles

So that means that the angle next to x must be 40˚

So 40 + 20 + x = 180 (since it's half a circle)

60 + x = 180

x = 120
