Answer:
70°
Step-by-step explanation:
We know that the triangle is an iscoceles based on the 2 small lines drawn horizontally on 2 sides of the triangle.
We know that the base angles in an iscoceles triangle are the same, so the angle that has not been drawn is 55°.
55° + 55° = 110°
180° - 110° = 70° (180 comes from the entire triangle adding up to 180°)
Answer:
y - 4 = 6(x - 7)
Step-by-step explanation:
the equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a,b) a point on the line
here m = 6 and (a, b) = (7, 4), hence
y - 4 = 6(x - 7) ← in point-slope form
Answer:
a)ΔFHA is similar to ΔZIA by hypotenuse side test.
reason:- angle H and angle I are of 90 degrees.
b) FH/ ZI = HA/ IA = FA/ ZA
angle F = angle Z, angle H = angle I , angle angle A = angle A
The scale factor is 3/2......( HA/IA = 12/8 = 3/2)
c) IZ = 3.3 ....( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)
