Answer:
A=360in^2
Step-by-step explanation:
there are 5 faces, 2 triangular, 3 rectangular
Triangular:
A=(9 * 10)/2=45
Since there are 2 of them the total is 90 in^2 for the triangles
Rectangular:
A=10*9=90
Since there are 3 the total is 270in^2
Total surface area is A=270+90=360in^2
Answers:
x = 5
m∠C = m∠H = 38 degrees

Given that ABCD ≅ FGHJ
We know that corresponding angles of two congruent
quadrilaterals are equal
Therefore,
m∠A = m∠F
m∠B = m∠G
m∠C = m∠H
m∠D = m∠I
Given,
m∠C = 9x – 7
m∠H = 5x + 13
Since m∠C = m∠H
9x – 7 = 5x + 13
Add 7 to both sides of the equation
9x – 7 + 7 = 5x + 13 + 7
9x = 5x + 20
Subtract 5x from both sides of the equation
9x – 5x = 5x – 5x + 20
4x = 20
Divide both sides of the equation by 4
4x/4 = 20/4
x = 5
To determine the measures of angle C and angle H
m∠C = m∠H
We know that m∠C = 9x – 7
Since x = 5
m∠C = 9(5) – 7
m∠C = 45 – 7
m∠C = 38
Therefore, m∠C = m∠H = 38 degrees

Answer:
x = 17.74 cm
Step-by-step explanation:
tan 29 = x/32
0.5543 = x/32
x = 17.74 cm
Bring y to one side and the rest to the other switching the positives to negative then you’ll get Y=114
