Answers

Answer 1

Answer:

The value of x= 7 and that of Angle A= 157°

Step-by-step explanation:

(x+16)° = (4x-5)° [Vertically opposite angles]

3x= 21

x= 7

Now, A + (4x-5)° = 180° [Linear pair]

A + [4(7)-5] = 180°

A + 23 = 180°

A = 180° - 23

A = 157°

Hope it helps you

Answer 2
(x + 16) = (4x - 5)

x + 16 = 4x - 5

16 + 5 = 4x - x

21 = 3x

3x = 21

x = 21/3

x = 7

Triangle KJL ≅ Triangle MJL (RHS)

[JL = JL(common), KL = LM(given), angle KLJ = angle MLJ(given)]

we come up to the conclusion that 4x + 6 = 3x + 10

x = 4

∴angle KJL = 4(4) + 6 = 22°

22 degrees is the right answer

what is the measure of the base angle,x, of the isosceles triangle shown below? round your answer to the nearest tenth of a degree.​

Answers

Answer:

x ≈ 49.7°

Step-by-step explanation:

Since, the given triangle is an isosceles triangle,

Two sides having measure 17 units are equal.

Opposite angles of these equal sides will be equal.

Measure of the third angle = 180° - (x + x)°

By sine rule,

[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(180-2x)}{22}[/tex]

[tex]\frac{\text{sinx}}{17}=\frac{\text{sin}(2x)}{22}[/tex] [Since, sin(180 - θ) = sinθ]

[tex]\frac{\text{sinx}}{17}=\frac{2(\text{sin}x)(\text{cos}x)}{22}[/tex]

[tex]\frac{\text{sinx}}{17}=\frac{(\text{sin}x)(\text{cos}x)}{11}[/tex]

[tex]\frac{1}{17}=\frac{(\text{cos}x)}{11}[/tex]

cos(x) = [tex]\frac{11}{17}[/tex]

x = 49.68°

x ≈ 49.7°

A farmer takes 1 day to fill 7 bins of corn. At this rate, how long will it take to fill 560 bins?

Answers

It will take him 80 days
The way you solve that is for every day the farmer is filling 7 bins of corn. So if he needs to fill 560 bins of corn you just divide 560/7 and that equal 80. So the answer would be 80 days.

A regular pentegon is divided into five identical isosceles triangles. The area of the regular Pentagon is Bcm^2 . Write a formula for T, the area of one of the triangles

Answers

Answer:

B/5

Step-by-step explanation:

A regular pentagon has five sides of equal lengths. If each vertex of the regular pentagon is connected to its centre, you would have five identical isosceles triangles.

Hence, the five triangles all have equal areas. If the area of a triangle is Xcm², then

5X = B

Find the measure of CB.

Answers

Answer:

I'm Pretty Sure Its 40.

Step-by-step explanation:

Answer:

CB = 20.

Step-by-step explanation:

If the triangle is Isosceles, assuming that <D = <B according to the markings, CB must be 20 since 32 is the greatest side and therefore the hypotenuse, 20 is the smaller side and therefore either opposite or adjacent. Given that two sides must be the same, since CB is opposite of angle D which is congruent to angle B, CB = side opposite of angle B = 20.
