Answer:

∠RQS = 100°

Step-by-step explanation:

The angles 5x + 5 and 11x - 65 form a linear pair. That is they sum to 180°

Sum the 2 angles and equate to 180, that is

5x + 5 + 11x - 65 = 180

16x - 60 = 180 ( add 60 to both sides )

16x = 240 ( divide both sides by 16 )

x = 15

∠RQS = 11x - 65 = (11 × 15) - 65 = 165 - 65 = 100°

Combination = doesn't matter what order
Permutation = order matters

There are <u>two</u> methods to work out combinations.

Method 1 List out possibilities
123 124 125 126 127 134 135 136 137 145 146 147 156 157 167
234 235 236 237 245 246 247 256 257 267
345 346 347 356 357 367
456 457 467
567

For a total of 35 combinations.

Method 2 Use a formula.
It's a rather complicated one, so only use it if you have a lot of possibilities.

$\frac{n!}{r!(n-r)!} = \frac{7!}{3!(7-3)!} = \frac{7!}{3!*4!} = \frac{7*6*5*4*3*2*1}{3*2*1*4*3*2*1} = \frac{7*6*5}{3*2*1}=\frac{210}6=35$

(n is the number of choices, r is the amount you choose, and ! is a function that multiplies together all numbers down to 1)

Actually help on this one plz

Given the fact that AB≈AD, then 35 is also the angle measure of ADB. The sum of the angles of a triangle =180. 35+35=70. 180-70=110
