Answer:

No because one is bigger than the other and the smaller one has a 90 degree angle and the big one has a 60 and 70 degree angle

Answer:

No, they are not similar

Step-by-step explanation:

The three triangle angles should always add up to 180 degrees.

In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.

In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.

In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

Answer:

x = 80

Step-by-step explanation:

$22 \degree = \frac{1}{2} (x \degree - 36 \degree) \\ \therefore \: 22 \degree \times 2 = (x \degree - 36 \degree) \\ \therefore \: 44 \degree = x \degree - 36 \degree \\ \therefore \: 44 \degree + 36 \degree= x \degree \\ \therefore \: x \degree = 80 \degree \\ \: \: \: \: \: \huge \red{ \boxed{ \therefore \: x = 80 }}$
