Answer:
Step-by-step explanation:
Top triangle:
The hash marks indicate congruence. So, x is congruent to 15 or x= 15
x+6= 21
The length of the sides of this triangle are 15,15, and 21.
Two sides are congruent so isosceles.
Bottom triangle:
The sum of the angles in a triangle is 180.
30+35+x=180
75+x=180
x=105
105> 90, so this is an obtuse triangle.
Answer:
(a) Altitude
(b) perpendicular bisector
(c) median
Step-by-step explanation:
- The perpendicular bisector of a side of a triangle is a line <u>perpendicular </u>to the side and passing through its midpoint.
- The angle bisector of an angle of a triangle is a straight line that <u>divides the angle</u> into t<u>wo congruent angles</u>.
- A median of a triangle is a line segment drawn <u>from a vertex</u> to the <u>midpoint</u> of the opposite side of the vertex.
- An altitude of a triangle is the <u>perpendicular</u> segment <u>from a vertex</u> of a triangle <u>to the opposite side</u> (or the line containing the opposite side).
(a) Altitude
m∠KML = 90° but JM ≠ ML (so not perpendicular bisector)
(b) perpendicular bisector
AD = DB and m∠BDE = 90°
(c) median
QS = QR ⇒ S is the midpoint QR, BUT it is not perpendicular to QR, so median

Answer:
Step-by-step explanation:
Replacing X with -3 ves you -2(-3) + 5 > 13. -2(-3) is 10 + 5 > 13. 10 + 5 gives you 15, which is greater than 13.
