Answers
Answer:
27.7°
Step-by-step explanation:
To find m<A, apply trigonometric function.
Reference angle = A
Side length opposite to A = 20
Hypotenuse = 43
Apply SOH, which is:
[tex] Sin (A) = \frac{Opp}{Hyp} [/tex]
Plug in the values
[tex] Sin (A) = \frac{20}{43} [/tex]
[tex] A = sin^{-1}(\frac{20}{43}) [/tex]
A ≈ 27.7° (nearest tenth)

Answers
Answer:
Step-by-step explanation:
Perimeter of the triangular base = 10 + 10 + 16
= 36 ft
Height of the prism = 15 ft
Base area = Area of the triangle
= [tex]\frac{1}{2}(\text{Base})(\text{Height}})[/tex]
= [tex]\frac{1}{2}(16)(6)[/tex]
= 48 square ft
Surface area of the triangular prism = 2(base area) + (perimeter × height)
= 2(48) + 36(15)
= 96 + 540
= 636 square ft
Garth has a collection of postcards from

them in albums. Each album holds
480 postcards. His collection already
fills two albums and one-fourth of
another album. How many postcards
does Garth have?
Answers
Answer:
1080
Step-by-step explanation:
480 + 480 + 1/4(480) = 1080
Answer:
1080 postcards
Step-by-step explanation:
WIth 2 full albums you take 480 and multiply it by 2 to get 960 and 1/4 of 480 is 120 because we divide 480 by 4 to get that and if we add 120 to 960 we get 1080.

x = √88.25 ≈ 9.4x = 15Step-by-step explanation:
1. x is the hypotenuse of a right triangle with legs 4.4 and 8.3. The Pythagorean theorem can be used.
x² = 4.4² +8.3² = 19.36 +68.89 = 88.25
x = √88.25 ≈ 9.394

Explanation:-
They have a rectangle ABCD as shown below, where AB = 24cm BC = 10cm and AE = 13cm
A. Calculate the volume of the rectangle ABCD
B. Calculate the circumference of the BCD triangle
C. Calculate the circumference of the BEC triangle
D. Calculate the circumference of the DEC triangle
Answers
Answer:
A. Area of ABCD = 240 [tex]cm^{2}[/tex]
B. 60 cm
C. 36 cm
D. 50 cm
Step-by-step explanation:
Given: AB = 24cm BC = 10cm and AE = 13cm.
A. Since a rectangle is a 2 dimensional figure, it has no volume but area.
So that,
the area of the rectangle ABCD = length x width
= 24 x 10
= 240 [tex]cm^{2}[/tex]
B. To calculate the circumference of the BCD triangle, apply the Pythagoras theorem to determine BD.
[tex]BD^{2}[/tex] = [tex]BC^{2}[/tex] + [tex]DC^{2}[/tex]
= [tex]10^{2}[/tex] + [tex]24^{2}[/tex]
= 676
BD = [tex]\sqrt{676}[/tex]
= 26
BD = 26 cm
so that,
the circumference of BCD = 10 + 24 + 26
= 60 cm
C. To calculate the circumference of the BEC triangle,
AC = 26 cm, AE = 13 cm
CE = 26 - 13
= 13 cm
CE = 13 cm
The circumference of the BEC triangle = 13 + 13 + 10
= 36 cm
D. The circumference of the DEC triangle = 13 + 13 + 24
= 50 cm

We’ll start by converting the 2/3 to 6ths so we have a common denominator.
Look at the denominator first. 3 x 2 is 6, so we need to multiply the numerator by 2 as well. 2/3 = 4/6.
So we have 1 4/6 + 1 5/6 = 2 9/6
But you know they’ll want you to reduce that so it’s 3 3/6...or 3 1/2.
Let me know where you have questions.
