Answer:
60m
Step-by-step explanation:
height =2+2×(let x be the length of the base)
area=1/2bh
30=1/2(2+2×)
30=2/2+2×/2
30=1+2×/2
30=1+×
30-1=×
29=
height=2+2×
2+2(29)
2+58
60
therefore the height is 60m
Answer:
3. isosceles, acute
5. scalene, obtuse
Step-by-step explanation:
3. Two (and only two) sides are the same length (and their opposite angles are the same measure), so the triangle is isosceles. All angles are less than 90°, so the triangle is acute.
__
5. All angles have different measures, so the triangle is scalene. The largest angle is greater than 90°, so the triangle is obtuse.
