Answer:

[tex]50^{\circ}[/tex]

Step-by-step explanation:

Complementary angles mean that the sum of the angles add up to [tex]90^{\circ}[/tex]. We can use algebra to solve for [tex]x[/tex] and then to determine [tex]m\angle QRS[/tex].

[tex]m\angle QRS + m\angle SRT = 90[/tex]

[tex]8x+10 + 8x = 90[/tex]

[tex]16x = 80[/tex]

[tex]x = 5[/tex]

[tex]m\angle QRS = 8x+10[/tex]

[tex]= 8(5)+10[/tex] (substitution)

[tex]=50^{\circ}[/tex]

∴ [tex]m\angle QRS = 50^{\circ}[/tex]

The perimeter of a rectangular garden is 338 m.
If the width of the garden is 74 m, what is its length?

Answers

Answer:

l=95

Step-by-step explanation:

Perimeter is all the sides add up. So the equation if you know two of the sides, it should be: 338=(2*74)+(2*l)

Answer:

Step-by-step explanation:

the perimeter is 2w plus 2l

so 338 = 74(2)+2l

338 = 148+2l

190=2l

l=95

your length would be 95 m

X, Y and Z form the vertices of a triangle, where ∠ YXZ = 68°, XY = 7.3m and XZ = 8.3m. Calculate the area of the triangle. Round your answer to 1 DP.

Answers

Answer: Area = 28.2m²

Step-by-step explanation: The triangle YXZ is shown in the figure below.

Area of a triangle is calculated by the formula:

[tex]A=\frac{1}{2} (base*height)[/tex]

According to the figure, the base of this triangle is b = 8.3m.

Height is a perpendicular line created from one side and intersecting the opposite angle.

To determine the height, use trigonometric relations to angle 68:

[tex]sin(68)=\frac{h}{7.3}[/tex]

h = 7.3*sin(68)

h = 7.3*0.93

h = 6.8

Now, area of triangle YXZ is

[tex]A=\frac{1}{2} (8.3*6.8)[/tex]

A = 28.2

Area of triangle YXZ is 28.2m².

Together, teammates Pedro and Ricky got 2675 base hits last season. Pedro had 277 more hits than Ricky. How many hits did each player have?

Answers

Answer:

1199 for ricky, 1476 for Pedro

Step-by-step explanation:

2675-277=2398

2398 / 2 = 1199

each player had 1199 bases, pedro however, had 277 more bases than ricky

1199 + 277 = 1476

By solving a system of equations, we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.

How many hits did each player have?

Let's define the variables:

P = base hits of Pedro last season.R = base hits of Ricky last season.

Then we have that the total number of base hits last season is 2675, so we have:

P + R = 2675

We also know that Pedro has 277 more hits than Ricky, then:

P = 277 + R

To solve these equations, we can replace the second equation into the first one:

P + R = 2675

(277 + R) + R = 2675

2*R = 2675 - 277 = 2,398

R = 2,398/2 = 1,199

So we conclude that Ricky has 1,199 base hits, and Pedro has 1,476 base hits.
