Answer:

5) 112°

6) 40°

Step-by-step explanation:

5) The angle E or ? is half the sum of the intercepted arcs:

? = (130° +94°)/2 = 112°

6) The angle D is half the difference of the intercepted arcs:

? = (135° -55°)/2 = 40°

Since it doesn't give us a specific variable to use I'll just use y. and my phone doesn't have the less than or equal to sign so ill just say how to draw it i guess.
41. y (less than sign with line) 4.
42. y × (-7) > 42
43. y ÷3 - 5 (greater than sign with line) 11

and im not 100% sure on 44 so... anyway you probably know what the greater than or equal to sign and the less than or equal to sign are so. yeah hope it helped.

Answer:

right

neither

straight

neither

Step-by-step explanation:

The first angle is a right angle. The box in the corner indicates a 90 degree angle

The second angle is less than 90 degrees so it is an acute angle

The third angle is a straight line so it is a straight angle.

The fourth angle is wider than 90 degrees it is an obtuse angle

Answer:

5 × $\frac{1}{100}$

Step-by-step explanation:

$4*100+2*10+3*1+6*\frac{1}{10}+x+9*\frac{1}{1000}=423.659\\4*100+2*10+3*1+6*0.1+x+9*0.001=423.659\\400+20+3+0.6+x+0.009=423.659\\423.609+x=423.659\\x=0.05\\\\50*\frac{1}{10}=5\\\\5*\frac{1}{100}=0.05\\\\50=50\\\\5*0.05=0.25$
