Answer:

80 degrees

Step-by-step explanation:

A triangle has 180 degrees so you have to add up the two angles with measurements you know (70 + 30= 100) and subtract 100 from 180

A: It would be 80 degrees. :)
E: This is because all triangles equal 180 degrees so if you already have 2/3 angles then it’s pretty easy to determine the last angle. Angle B + Angle A = 100 (70+30=100). So just subtract 180 by 100 and you get 80 degrees!

When solving 5 (<br>25) - 7. What is the correct sequence of operations? (5 points)

You would multiply 5 by 25 (125) and then subtract 7 (118). Parentheses, exponents, multiply/divide, then add/subtract.

Compute 41, 42, 43, 44, 45, 46, 47, and 48. Make a conjecture about the units digit of 4n where n is a positive integer. Use str

padilas [110]

Answer:

The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even

Step-by-step explanation:

$4^1 = 4\\4^2 = 16\\4^3 = 64\\4^4 = 256 \\4^5 = 1024\\4^6 = 4096\\4^7 = 16384\\4^8 = 65536$

The conjecture is that the unit digit of 4^n = 4 when n = odd also 4^n = 6 when n = even

To prove this conjecture

$4^1 = 4\\4^2 = 16$ unit digit = 6

hence the property is true for ; n = 1 and n = 2 and also for every odd and even number ( i.e. from 1 to 8 )
