Answer:
0
Step-by-step explanation:
→ First find inverse cosine 1/2
60°
→ Now multiply this answer by 3 because then if you substitute it in you get 0.5
∝ = 180°
→ Now find sine of 180°
0
Step-by-step explanation:
By Exterior Angle Theorem,
(x + 40)° + (4x - 5)° = (6x + 20)°
Therefore 5x + 35 = 6x + 20 and x = 15.
Hence angle QPT = (6 * 15 + 20)° = 110°.
Answer:
836m
Step-by-step explanation:
Answer: 3 inches wide (estimated orignially it came up to 2.65)
2 inches length
Step-by-step explanation:
Answer:
(x-5) (x-2)
Step-by-step explanation:
x^2 (-2x-5x) +10
basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
