Answer:-3
Step-by-step explanation:
know
a+b=1
a-b=2
by combine the equatio you will get 2a+b-b=3
the b cancal each other out left 2a=3 and 3/2 = 1.5 for a
so if 1.5=a then apply 1.5 into a+b=1 and a-b=2 you will receive -.5 for b and 1.5/-.5 will equal to -3
An obtuse triangle has a obtuse angle that measures larger than 90 degrees.
You have to apply the Phytagorean Teorem, which is:
c^2 = a^2 + b^2
c=√(a^2 + b^2)
"c" is the hypotenuse.
"a" and "b" are the legs of the triangle (10 inches and 15 inches).
Let's substitute those values in the equation:
c=√(a^2 + b^2)
c=√(10^2 + 15^2)
c=√325
c=18 inches
What is the smallest possible whole-number length of the unknown side?
It is the next largest integer greater: 19 inches.
Answer:
23
Step-by-step explanation:
The given two triangles are congruent , by SSS congruence condition , therefore the corresponding sides will be equal .
=> x - 4 = 19
=> x = 19 + 4
=> x = 23
