Angle A and angle B are supplementary. The measure of angle A is 4 less than 7 times the measure of angle B. Find the measure of

Alexeev081 [22]

A = 157, B = 23 The definition of supplementary angles is that they add up to 180 degrees. So A+B = 180. And A = 7B - 4. So write down the formula A + B = 180 Substitute the formula for A in terms of B 7B - 4 + B = 180 Combine terms 8B - 4 = 180 Add 4 to both sides 8B = 184 Divide both sides by 8 B = 23 Now calculate A in terms of B A = 7B - 4 A = 7 * 23 - 4 = 161 - 4 = 157 Verify that A and B add up to 180 157 + 23 = 180

Using a trigonometric ratio to find a side length in a right triangle. ROUND TO THE NEAREST TENTH ‼️ Can someone help me please❓

SSSSS [86.1K]

Answer:

x ≈ 34.9

Step-by-step explanation:

Using the sine ratio in the right triangle

sin35° = $\frac{opposite}{hypotenuse}$ = $\frac{20}{x}$

Multiply both sides by x

x × sin35° = 20 ( divide both sides by sin35° )

x= $\frac{20}{sin35}$ ≈ 34.9 ( to the nearest tenth )

As students move to thinking about formulas it supports their conceptual knowledge of how the perimeter of rectangles can be put

kolezko [41]

Answer:

B. $P=l+w$

Step-by-step explanation:

Let l represent length of rectangle and w represent width of rectangle.

We have been given four formulas for the perimeter of rectangle. We are asked to choose the formula that displays a common student error for finding the perimeter.

We know that perimeter of a polygon is sum of all sides of the polygon. We also know that rectangle is polygon having two sets of equal sides.

The perimeter, P, of rectangle will be sum of its all sides that is:

$P=l+w+l+w$

Combine like terms:

$P=2l+2w$

Factor out 2:

$P=2(l+w)$

Upon looking at our given choices, we can see that formula represented by option B displays a common student error for finding the perimeter.
