Answer:
<ABC = 15
< BAC = 150
Step-by-step explanation:
<C = <B since this is an isosceles triangle. We know this because AC = AB
<C = 15 so <ABC = 15
The sum of the angles of a triangle is 180
A + B+ C = 180
A + 15+15 = 180
A +30 =180
A = 180-30
A = 150
< BAC = 150
578 bc 2 goes into 578 evenly

Translation: Can you help me to solve by please substitution method.
{5x+7y=-1
{-3x+4y=-24
Step-by-step explanation:
Given the simultaneous equation.
5x+7y=-1 .....1
-3x+4y=-24 .....2
From equation 2, making y the subject of formula.
4y = -24 + 3x
y = (-24+3x)/4 ...... 3
Substituting the equation 3 into equation 1
5x+7((-24+3x)/4) = -1
Multiply through by 4
20x + 7(-24+3x) = -4
20x - 168 + 21x = -4
41x -168 = -4
41x = -4 + 168
41x = 164
x = 164/41 = 4
x = 4
Substituting x = 4 into equation 3
y = (-24+3(4))/4
y = (-24+12)/4
y = -12/4
y = -3
Answer:
25, 29
Step-by-step explanation:
The Pythagorean Theorem is a² + b² = c² where a and b are legs and c is the hypotenuse. In this case, a = 2, b = 5 and we are solving for c, which is also known as AC here. Therefore,
4 + 25 = AC²
AC² = 29
