Answer:
m∠KPL = 90°
m∠NPM = 27°
m∠MPL = 63°
m∠JPK = 27°
m∠NPJ = 153°
Step-by-step explanation:
There's a 90° angle in m∠NPL so we can already identify the measure of m∠NPM which is 27° because 63° + 27° = 90° angle.
m∠MPL is GIVEN as 63° in the question!!!
and I'm pretty sure m∠JPK = m∠NPM which is 27°
m∠KPL is 90°. everytime you see a box around that angle, it means the angle measures 90°
Finally for m∠NPJ we add up all of the values that we already know minus the total measure which is 360°.
Explanation: total measure: 360°. 90° + 27° + 63° + 27° = 207.
360° - 207° = 153°

Please help calculate the surface area
Answers
Answer:
SA = 189 cm^2
Step-by-step explanation:
What you're going to want to do is calculate the surface area of each type of side (triangle or rectangle) then add them up accordingly!
Starting with triangles: area = 1/2 * l * h
So, in this scenario its (1/2) * 6 * 4 , or half of 24, which is 12 cm^2
Since we have two triangular sides, that totals to 24 cm^2.
Then the rectangular sides: area = l*h
so, 5*11 = 55 cm^2
We have three rectangular sides, totalling 165 cm^2
165+24 = 189 cm^2
Answer:
200 [tex]cm^{2}[/tex]
Step-by-step explanation:
SA = LA + 2B where LA is the lateral area and B is the area of the base(triangle)
LA = ph p = perimeter of base and h = distance between bases
LA = (5 + 5 + 6)11 = 176
B = bh/2 = 6(4)/2 = 12
SA = 176 + 2(12) = 176 + 24 = 200 [tex]cm^{2}[/tex]

Answers
Answer:
Here we want to solve:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
First, remember the two expansions:
(a + b)^2 = a^2 + 2*a*b + b^2
(a - b)^2 = a^2 - 2*a*b - b^2
Using these relations, we can expand:
(cos(A) + sin(A))^2 = cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2
( sin(A) - cos(A))^2 = sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2
Replacing that in our equation, we geT:
(cos(A)^2 + 2*cos(A)*sin(A) + sin(A)^2) + (sin(A)^2 - 2*sin(A)*cos(A) + cos(A)^2) = 2
We can simplify this to get:
2*cos(A)^2 + 2*sin(A)^2 + 2*cos(A)*sin(A) - 2*cos(A)*sin(A) = 2
2*cos(A)^2 + 2*sin(A)^2 = 2
We can take the 2 as a common factor to get:
2*cos(A)^2 + 2*sin(A)^2 = 2*( cos(A)^2 + sin(A)^2) = 2
Now we can divide both sides by 2:
2*( cos(A)^2 + sin(A)^2)/2 = 2/2
cos(A)^2 + sin(A)^2 = 1
And this is a trigonometric property that is true for any value of A.
So the equality:
(cos(A) + sin(A))^2 + ( sin(A) - cos(A))^2 = 2
is true for any real value of A.

Step-by-step explanation:
Surface area is the area of each side of the shape added together. So in this situation, it would be the area of a side, multiplied by 6, because a square has six sides.
To find the area, it's length x width. You're given the length and width, which both are 4.3 mm.
4.3 x 4.3 = 18.49
With this new number, you're gonna multiply it by 6. And the total will be 110.94 mm. :)

Answer:
2. 3/4, 50%, 1/4, 12.5%

Work completed at the 4 sites = 1/4, 50%, 12.5%, 3/4
1/4 = 0.25
50%
= 50/100
= 0.5
12.5%
= 12.5/100
= 0.125
3/4
= 0.75
in order from greatest to least?
3/4, 50%, 1/4, 12.5%
1. 12.5%, 1/4, 50%, 3/4
