Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°
Answer:
x=31°, y=52°,z=97°
Step-by-step explanation:
The interior angles of a triangle sum up to 180°
y°+ 31°+ 97°= 180°
y° = 180 - 31° - 97°
y=180°-128°
y° = 52°
Alternative angles are equal
x= 31°
Two opposite angles of a parallelogram are equal
z°= 97°
Therefore x=31°,y=52° and z=97°
The last choice is correct.
The answer is 14 because 5 multiplied by 2 is 10+4 is 14
Answer: See explanation
Step-by-step explanation:
Your question isn't well written but let me help out by making some assumptions.
Let's say Jamie's older brother and his three friends want to split the cost of lunch that costs $30 and they also want to leave a 20% tip. How much should each person pay?
Cost of the lunch = $30
Tip = 20% × $30 = 0.2 × $30 = $6
Total amount to be paid = $30 + $6 = $36
Since there are four people and they want to share the cost, each person would pay:
= $36 / 4
= $9
It would be: (1 + 3i) + (2 - 5i)
= 3 + 3i - 5i
= 3 - 2i
In short, Your Answer would be Option B
Hope this helps!
