Line HF is tangent to circle D at point E. SEgment DE is the radius of circle D, what is true about DEF?A.angle DEF is congruent to angle DEH
B.angle DEF is an acute angle
C.angle DEF is an obtuse angle
D.angle DEF is a straight angle

Answers

Answer 1

Answer:

When we draw a circle with the centre at D and have a tangent HF to the circle D at point E, the angle DEF will be a right angle.

In other words angle DEF = 90 degrees

Since HF, the tangent, is a straight line, the other angle DEH should also be = 90 degrees because the straight line has an angle of 180 degrees

Therefore angle DEF = angle DEH = 90 degrees

Therefore, angle DEF is congruent to angle DEH (Option A)

Answer 2

Answer: D.angle def is an obtuse angle

949 rounded to the nearest ten

Answers

949 rounded to the nearest ten would be 950 because 5 and above rounds up to the next 10.

950 because round up when its 6or more and down when its 5 or less like 367 seven is more than 5 so you go up to 370 rounded to the nearest ten

Can you solve 2/3(x+13)=22

Answers

$\frac { 2 }{ 3 } \left( x+13 \right) =22\n \n \frac { 3 }{ 2 } \cdot \frac { 2 }{ 3 } \left( x+13 \right) =22\cdot \frac { 3 }{ 2 }$

$\n \n x+13=\frac { 66 }{ 2 } \n \n x+13=33\n \n x=33-13\n \n x=20$

$(2)/(3)(x+13)=22\n2(x+13)=66\n2x+26=66\n2x=40\nx=20$
