15)
an exterior angle equals the sum of the remote interior angles
<span>so
m<XYT = m<X + m<Z
4x - 25 = x + 15 + 50 - 3x
4x - 25 = -2x + 65
6x = 90
x = 15
answer
x = 15

Answer:
angle B is 38°
Step-by-step explanation:
all angles in a triangle has to equal 180°.
So first find the measurement of angle BAD. This is done by subtracting angle of CAD=46° from the total angle CAB=78° to get 32° for angle BAD. So if angle ADB is 110° and angle BAD is 32° which equals (110+32=) 142.
Then take 180 - 142 = 38°
Answer:
7 students.
Step-by-step explanation:
10% of 70 is 7.
well it would be 17=1/3+13
Answer:
26
Step-by-step explanation:
→ Utilise Pythagoras theorem
a² + b² = c²
→ Substitute in the values
10² + 24² = c²
→ Simplify
100 + 576 = c²
→ Simplify further
676 = c²
→ Square root both sides to isolate c
26 = c
