Answer:
∠5=∠7=∠6=∠8=143°
∠4=∠2=∠1=37°
Step-by-step explanation:
∠4=180-∠6=180-143=37°
Answer:
x = 25
Step-by-step explanation:
x + 25 + 2x - 10 + 90 = 180
3x + 105 = 180
3x = 75
x = 25
Answer:
X = 0, π/2 in the interval [0, 2pi).
Step-by-step explanation:
Use the auxiliary angle method:
R sin(x + a) = Rsin x cos a + Rcos x sin a = 1
sin x + cos x = 1
Comparing coefficients:
R cos a = 1 and R sin a = 1, so
tan a = R sin a / R cos a = 1
So a = π/4 radians.
Also R^2(sin^2 a + cos^2 a) = 1^2 + 1^2 = 2
Therefore R = √2.
So √2 sin (x +π/4 = 1
sin x + π/4 = 1/√2
x + π/4 = π/4
x = 0 radians
Also
x = 0 + π/2 = π/2.

Answer:
To find the missing base, you simply divided the area by the given height. This will work the same way if you are looking for the height. To find the missing height, divide the area by the given base.
Step-by-step explanation:
base = 35cm, height = ? cm, and a = 700 cm^2 a = bh
700 = 35 x h
700/35 = 35 x h/35
20 = h
Therefore, the answer would be 20cm. Hope this helps! :)
