Answer triangle RST is congruent to the triangle LMK
If you move the triangle vertically you can find the congruency of two sides and one angle
Answer:
B 204 bc 34x6 =204
Step-by-step explanation:
X in the math problem is negative two
x+y+z=15
y =2x
z=y-20
substitute these equations into the first
x+2x+y-20 =15
now substitute 2x in for y
x + 2x +2x-20 =15
combine like terms
5x-20 =15
add 20 to each side
5x = 35
divide by 5
x=7
y =2x
y =14
z = y-20
z=14-20
z=-6
The third number is -6
Answer:
Step-by-step explanation:
- sum of inner angles of a triangle = 180 degrees
angle A = 180 - (90+23) = 180 - 113 = 67 degrees
- sin (23) = 0.390731
sin = opposite/hypotenuse
opposite = sin * hypotenuse
AC = 0,390731 * 34 = 13.3
- cos (23) = 0,920505
cos = adjacent/hypotenuse
adjacent = cos * hypotenuse
BC = 0,920505 * 34 = 31.3
