Answer:
78
Step-by-step explanation:
∠A + ∠B + ∠C = 180 { Angle sum property of triangle}
42 + ∠B + 60 = 180
∠B + 102 = 180
∠B = 180 - 102 = 78
In similar triangles, corresponding angles are congruent.
∠S ≅ ∠B
∠S = 78°
Answer:
20n
Step-by-step explanation:
One pretzel has 20 calories. Write an algebraic expression for the total number of calories in n pretzels.
1 pretzel = 20 calories
n pretzel = x
Cross Multiply
x × 1 pretzel = n pretzel × 20 calories
x = n pretzel × 20 calories/1 pretzel
x = 20 n
Therefore, an algebraic expression for the total number of calories in n pretzels = 20n
Answer:
60
Step-by-step explanation:
Answer:
Solution given:
For rectangle
length [L]=BC=16in
breadth [b]=AB=4in
For traingle
length[l]=8in
breadth [b]=3in
total area =area of rectangle ABCD+2×area of triangle DEF
=L×b+2×1/2×[b×h]
=16×4+8×3=88in² is your answer
