Match the given conditions to the number of triangles that can be constructed from them. given conditions:
-The lengths of the three sides are 4 centimeters, 2 centimeters, and 7 centimeters.
-The measures of two angles are 30 and 60% and the length of the included side is 12 inches.
-The measures of the three angles are 45°, 75°, and 60°.

Number of Triangles Glven Conditions:
- Infinitely many
-1
-0

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
