Answer:
Step-by-step explanation:
Statements Reasons
1). m∠QPS = m∠TPV 1). Given
2). m∠QPS = m∠1 + m∠3 2). Angle addition postulate
m∠TPV = m∠2 + m∠4
3). m∠1 + m∠3 = m∠2 + m∠4 3). Given
4). m∠1 = m∠2 4). Given
5). m∠1 + m∠3 = m∠2 + m∠4 5). Subtraction property
m∠3 = m∠4
Answer: 90
Step-by-step explanation:
Answer:
The second and fourth one is right
Step-by-step explanation:
A²+ B² = C²
15² + 20² = 25²
225 + 400 = 625
625 = 625
16² + 30² = 34²
256 + 900 = 1156
1156 = 1156

Answer:
40°, 80°, 120°, 120°
Step-by-step explanation:
sum the parts of the ratio, 1 + 2 + 3 + 3 = 9 parts
The sum of the interior angles of a quadrilateral is 360°
Divide this by 9 to find the value of one part of the ratio.
360° ÷ 9 = 40° ← value of 1 part of the ratio
Then
2 parts = 2 × 40° = 80°
3 parts = 3 × 40° = 120°
The 4 angles are 40°, 80°, 120°, 120°
