Answer:
I call this angle chasing or angle hunting. The answer is 60°.
Step-by-step explanation:
![m \: bad = 25 \\ m \: bcd = 70 \: therefore \\ m \: adc \: = 180 - (70 + 25) = 85](https://tex.z-dn.net/?f=m%20%5C%3A%20bad%20%3D%2025%20%5C%5C%20m%20%5C%3A%20bcd%20%3D%2070%20%5C%3A%20therefore%20%5C%5C%20m%20%5C%3A%20adc%20%5C%3A%20%20%3D%20180%20-%20%2870%20%2B%2025%29%20%3D%2085)
since ∆ BAD is an isosceles triangle m BDA = m BAD = 25°
![m \: adc \: - m \: adb = 85 - 25 = 60 \\ x = 60 \: degrees](https://tex.z-dn.net/?f=m%20%5C%3A%20adc%20%5C%3A%20%20-%20m%20%5C%3A%20adb%20%3D%2085%20-%2025%20%3D%2060%20%5C%5C%20x%20%3D%2060%20%5C%3A%20degrees)
Answer:
3n + 7 = 37
Step-by-step explanation:
n represents the number of guests seated at each of the large table.
There are 3 large tables.
So, total number of guests in large table = 3n
Number of guests in smaller table = 7
Hence, total number of guests = 3n + 7
But, it is given that the total number of guests = 37
Hence, 3n + 7 = 37
Answer:
360degrees
Step-by-step explanation:
right answer
Answer:
x = 9
Step-by-step explanation:
x²-18x+91 = 10
x²-18x+81 = 0
(x-9)(x-9)= 0
x = 9
check:
9² - 18 (9) + 91
81-162+91 = 10
