Directions: Find each missing measure. please help me find T and U

adoni [48]

Answer:

m∠U = 54°

m∠T = 72°

Step-by-step explanation:

The triangle shown is an isosceles triangle. Therefore, the 2 sides and angles that are marked must be congruent:

m∠S = m∠U

m∠S = 54°

m∠U = 54°

All angles in a triangle add up to 180°:

m∠S + m∠U + m∠T = 180°

54° + 54° + m∠T = 180°

108° + m∠T = 180°

m∠T = 72°

What is the solution of the equation x2 + 8x + 5 = 0?

Setler79 [48]

Answer:

x = -0.683 (3dp)

x = -7.317 (3dp)

Step-by-step explanation:

Step 1: Apply the quadratic formula

(-b±( $\sqrt{b^{2}-4ac}$ )) / 2a

a = 1 (x²)

b = 8 (8x)

c = 5 (5)

(-8±( $\sqrt{8^{2}-4 x 1 x 5}$ )) / 2 x 1

Step 2: Simplify

(-8±( $\sqrt{44}$ )) / 2

Step 3: Solve

You need to replace the ± with first a + and then a -.

(-8+( $\sqrt{44}$ )) / 2 = -0.683 (3dp) = x

(-8-( $\sqrt{44}$ )) / 2 = -7.317 (3dp) = x

Hope this helps!

Write a function rule that produces an output of 7 for an input of 1.6

Karolina [17]

Here is a function rule that produces an output of 7 for an input of 1.6

f(x) = x + 5.4

when x = 1.6, f(x) = 1.6 + 5.4 = 7

3/4(x+5 1/2) = 5/8 Distributive Property Brainly

Talja [164]

Answer:

x = - $\frac{14}{3}$

Step-by-step explanation:

Given

$\frac{3}{4}$ (x + 5 $\frac{1}{2}$ ) = $\frac{5}{8}$

Multiply both sides by 8 to clear the fractions

6(x + 5 $\frac{1}{2}$ ) = 5 ← distribute parenthesis on left side

6x + 33 = 5 ( subtract 33 from both sides )

6x = - 28 ( divide both sides by 6 )

x = $\frac{-28}{6}$ = - $\frac{14}{3}$
