Answer:

A=20 degrees

Step-by-step explanation:

All of the interior angles of a triangle must add up to 180 degrees, so:

2x+5x+11x=180

18x=180

x=10

A=2(10)=20

Hope this helps!

Answer:

Angle A = 20 degrees

Step-by-step explanation:

The sum of the angles of a triangle is 180

A+ B+ C = 180

2x+5x+11x = 180

Combine like terms

18x = 180

Divide by 18

18x/18 = 180/18

x = 10

Angle A = 2x = 2*10 = 20

Angle B = 5x = 5*10 = 50

Angle C = 11x = 11*10 =110

Add together 2350mm 3.42cm 11/2m and 1.45m

Artyom0805 [142]

9.3342meters because you convert 2350mm into m which is 2.35m, + and also convert 3.42cm to m which is 0.0342 then + 1.45m +11/2m= 9.3342m

The perimeter of a rectangular field is 372 yards. If the width of the field is 87 yards, what is its length?__yards

worty [1.4K]

ANSWER

The length of the rectangular field is 99 yards

EXPLANATION

Given information

The perimeter of a rectangle field is 372 yards

The width of the field is 87 yards

To find the length of the rectangular field, follow the steps below

Step 1: Write the formula for finding the perimeter of a rectangular field

$\begin{gathered} \text{ The perimeter of a rectangular field = 2\lparen l + w\rparen} \\ \text{ where l =length, and w = width} \end{gathered}$

Step 2: Substitute the given data into the formula in step 1

$\begin{gathered} \text{ Perimeter = 2 \lparen l + w\rparen} \\ \text{ Perimeter = 372 yards} \\ \text{ width = 87 yards} \\ \text{ 372 = 2\lparen l + 87\rparen} \\ \text{ Divide both sides by 2} \\ \text{ }\frac{372}{2}\text{ = }\frac{2}{2}(l\text{ + 87\rparen} \\ 186\text{ = l + 87} \\ \text{ subtract 87 from each sides of the equation} \\ \text{ 186 - 87 = l + 87 - 87} \\ \text{ 99 = l} \\ l\text{ = 99 yards} \end{gathered}$

Hence, the length of the rectangular field is 99 yards

The length of a rectangle is 4x + 5 and the width is 8x - 4. what is the perimtleter?

Luda [366]

Hi there!

Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.

2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2

So, the perimeter is 24x + 2.

Hope this helps!

Principal argument for (√3-i)^6

True [87]

Answer:

r= $\sqrt{(\sqrt{3})^{6} +(1)^{2} } =\sqrt{4} =2$

(2)^5(cos(330.6)+isin(330.6))

=64(Cos1350+iSin1350)

64(cos180+isin180)

=64(-1+0)= -64

Step-by-step explanation:

3e <= 6

e <= 2 (divide 3 on both sides)

The e-values that satisfy the inequality are:

e = 1 and e = 2.
