Answer:
85º
Step-by-step explanation:
<7=<4 since we know the lines are parallel, and intersected at the same angle
Therefore, <7=85º.

Answer:
X = 67°
Step-by-step explanation:
The sum of every triangle’s interior angles is 180°. First subtract the given angle, 23°, from 180°. This equals 157°. Next you can see that one of the triangle’s angles has a right angle mark. This mark means it’s a right angle and all right angles are 90°. Take 157° and subtract 90°. This equals 67°. This means the remaining angle equals 67°.
Answer:
11.5 cm
Step-by-step explanation:
The dimensions of a right angled triangle can be determined using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
a² + 8² = 14²
a² + 64 = 196
a² = 196 - 64
a² = 132
find the square root of 132
a = 11.5 cm
