Answer:
what questions
Step-by-step explanation:
The answer is 40°
i will tell you how,
Total angle sum of any triangle is 180°
∠A + ∠B + ∠E = 180°
70° + 80° + ∠E = 180°
solve for ∠E
∠E = 30°
Now solve use ∠BDE,
∠B + ∠D + ∠E = 180°
20° + 90° + 30° + x = 180° (in triangle DEB, ∠E = 30 + x ) (∠D is 90°)
solve for x
there fore, x = 40°
Step-by-step explanation:
Given,
a=3,b=2,c=5
a)a(b+c)
=3(2+5)
=3×7
=21.
B)2ac^2
=2×3×(5)^2
=6×25
=150
Answer: There are no solutions.
Step-by-step explanation: So the way you do this is by subtracting 9p from both sides, which gets you:
8 = -7
Since 8 is not equal to -7, there is no solution to this equation.
