Order of operations so -6 × -5 = 30
-6 + 30 = 24 is the answer
Hope this helps!
Answer:
x=20
Step-by-step explanation:
we know the straight angle theorum...
3x+80+2x=180
5x=100
x=20
The answer is b both shapes are similar.<span />
Answer:
22.6 degrees
Step:
The hypotenuse is 13cm using pythagoras theorem.
Now, finding the smallest angle is by using;
SOH
sin = opposite over hypotenuse
Thus, cos^-1 (12/13)
=22.61
and equals to 22.6 (1d.p)
