The two triangles of similar to one another, the first smaller triangle have sides that are 15 ft, 12 ft, 18 ft. The Bigger triangle has sides that are 25 ft, 20 ft, 30 ft. What is the scale factor of the triangle? Will mark brainliest

angle addition postulate

2x=56

step-by-step explanation:

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52

step-by-step explanation:

df =

both have same length

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
