Take the inverse cosine of 0.5162
x=59 degree
Answer:
x = 24
Step-by-step explanation:
Act like it one triangle that has angle 94 and 41 but not the corner
all 3 angle of a triangkle equal 180
so to fine the missing corner you sub tract 180 by 94 and 41 (45)
Now that we know that angle we can find x for the small angle
180 - (111 + 45) = 24
Answer:
Step-by-step explanation:
substitute and solve:
100 = bh
100 = b(2b)
100 = 2b²
50 = b²
b = √50
b = √(25 * 2)
b = 5√2
solve for h:
h = 2b
h = 2(5√2)
h = 10√2
if you are told to round to 1 DP :
b ≈ 7.1 m
h ≈ 14.1 m
Answer:
No
Step-by-step explanation:
When you plug in (2,-2) into the equation, the solution does not equal 4. So the point (2,-2) does not lie on the line.
the area and circumference ones are correct. a quadrilateral has 4 sides, so that one is incorrect. hope this helps!
