Answer: 30 degrees
Explanation: the two triangles are proportional. Since the bottom triangle has two 75 degrees that add up to 150, 180-150=30. So the third unknown angle is 30 degrees and that goes for he sane on the top triangle too.
Answer:
Step-by-step explanation:
<u>Given</u>
- 0,324km+32mm+125cm+2,22dm+43dm= ? m
<u>Solution</u>
- 0.324 km = 0.324*1000m = 324 m
- 32 mm = 32/1000 m = 0.032 m
- 125 cm = 12/100 m = 1.25 m
- 2.22 dm + 43 dm = 45.22 dm = 45.22/10 m = 4.522 m
<u>Sum</u>
- 324 m + 0.032 m + 1.25 m + 4.522 m = 329.804 m
<u><em>Note. there is no dam unit, considered as dm</em></u>

Answer:
triangle on the left: 6 sq ft. triangle on the right: 28 sq ft. rectangle: 128. altogether, 162 sq ft. the trapezoid is about 61.6.
Step-by-step explanation:
for the rectangle the formula is bxh (base x height). for a triangle, it is bxh/2, or base times height divided by 2. for a trapezoid, it is b1+b2 x h / 2, or base 1 (bottom) plus base 2 (top) times height, take all of that and divide by 2.
